# Navigating Web Pages

In this section: Viewing Your Home Page Moving to Another Page Clicking a Link Retracing Your Steps Stopping and Reloading Visiting Bookmarked Pages Using My Sidebar

## Viewing Your Home Page

When you start Mozilla, you see Navigator, your browser. A "welcome" page entitled "Getting Involved with Mozilla" appears automatically in the browser window when you first launch Mozilla. This page welcomes you to the Mozilla community and tells you more about Mozilla. It has information on how you can report problems you find, and how you can participate in improving Mozilla. Suggested examples of this include contributing documentation, finding bugs, fixing bugs, and contributing new code.

Until you specify otherwise, this page is your home page. To choose your own home page, see Specifying How Mozilla Starts Up.

When you view web pages in Navigator, some pages are divided into rectangular areas called frames. Each frame can display other pages.

There are two ways to view more than one webpage simultaneously. The method most familiar to many people is opening a new window. To do this, open the File menu and choose New Navigator Window. At first the new window displays a copy of your home page, but you can use it to view a different page. The second way to accomplish this is to use a new feature available in Mozilla called "Tabbed Browsing." You are now able to open sub-windows or "tabs" within a single window. To open a new tab, press Control T or open the File menu and choose New | Navigator Tab. You will now see a second "tab" next to the original window you had open. Type in an address, such as www.mozilla.org in the location bar above the tab, to have the website corresponding with that website open in the open tab. The number of tabs you can open is only limited by the system resources available to you.

## Moving to Another Page

You move to a new page by typing its URL—its location (address) on the Web. URLs normally begin with the abbreviation "http://," followed by one or more names that identify the address. For instance, "http://netscape.com"

1. Click the Location Bar to select the URL that is already there.
2. Type the URL of the page you want to visit. The URL you type replaces any text already in the Location Bar.
3. Press Enter.

Tip: To quickly select the URL in the Location Bar, press Ctrl+L.

Location Bar

Don't know a URL? You can type part of a URL, such as "cnn" (for www.cnn.com); or you can type a general word, such as "gifts" or "flowers." Navigator guesses what page you want to view, or displays a page with a choice of links related to the word you typed.

[ Return to beginning of section ]

## Clicking a Link

Most web pages contain links you can click to move to other pages.

1. Move the pointer until it changes to a pointing finger. This happens whenever the pointer is over a link. Most links are underlined text, but buttons and pictures can also be links.
2. Click the link once. While the network locates the page that the link points to, status messages appear at the bottom of the window.

[ Return to beginning of section ]

## Retracing Your Steps

There are several ways to re-visit pages:

- To go back or forward one page, click the Back or Forward arrow.
- To go back or forward more than one page, click the small triangles on the Back and Forward buttons. You'll see a list of pages you've visited; to return to a page, choose it from the list.

Back Forward

- To see a list of any URLs you've typed into the Location Bar, click the arrow at the right end of the Location Bar. To view a page, choose it from the list.

Location Bar

- To choose from pages you've visited during the current session, open the Go menu and use the list in the bottom section of the menu.
- To choose from pages you've visited during the past several sessions, open the Tasks menu, choose Tools, then History. You see the history list. The history list displays a list of folders. Double clicking the folders displays subfolders or bookmarks to web pages. You can double-click the URL next to the Bookmark icon to view that page.

Tip: The My Sidebar History tab also allows you to choose from pages you've visited during the past several sessions. For information see adding My Sidebar tabs in "Customizing Mozilla". (Open the Help menu, choose Help and Support Center, and click Customizing Mozilla.)

### About History Lists

The history list contains links to recently visited pages.The Location Bar list contains links to pages you've typed into the Location Bar and then visited.

To access the history list from Navigator. Open the Task menu, choose Tools, then History. To access the Location Bar list, click the arrow at the right end of the Location Bar.

Tip: To quickly open the history list, press Ctrl+H.

If you don't want the Location Bar or history list to display the pages you've been visiting, you can clear the history list and Location Bar history entirely or selectively.

To delete all pages from the Location Bar or history list, begin from the Navigator window:

1. Open the Edit menu and choose Preferences.
2. Under the Navigator category, click History. (If no subcategories are visible, double-click the category to expand the list.)
3. Click Clear History and Clear Location Bar to remove all previously visited web pages from the lists.
4. If you wish to set a limit on how many pages remain in the history list, click the field next to "Number of pages in session history" and type a number of pages.

To selectively delete pages from the history list, do any of the following:

- To delete all pages from a domain, select a page within that domain (folder) in the History list, open the Edit menu, and select "Delete entire domain [domain name]." For example, use this command if you want to delete all pages that end in "netscape.com."
- To delete pages from a subdomain, select a page within that subdomain in the History list, open the Edit menu, and select "Delete all from [subdomain]." For example, use this command if you want to delete all pages from "health.netscape.com" but not "netscape.com."
- To delete a single page, select a page in the history list and press Delete.

Tip: To sort the history list, click one of the categories (Title, Location, or Last Visited). Click the title again to reverse the order.

## Stopping and Reloading

If a page is taking too long to appear, or you change your mind and don't want to view a page, click the Stop button.

To refresh the current page, or get the most up-to-date version, click Reload.

Reload | Stop

[ Return to beginning of section ]

## Visiting Bookmarked Pages

The addresses, or URLs, of web pages can be quite long and difficult to remember. Fortunately, it's not necessary to memorize URLs in order to browse the Web. Your browser has a list of bookmarks, which are pointers to interesting web pages.

To go to a bookmarked page, begin from the Navigator window:

1. Open the Bookmarks menu. The menu contains bookmarks represented by a bookmark icon, and folders that contain more bookmarks.
2. To visit a bookmarked page, choose a bookmark from the menu, or open a folder and choose a bookmark.

Tip: To retrace your steps, click the Back arrow.

You can save your own bookmarks to point to pages you frequently visit, or to other interesting places on the Web. See Creating New Bookmarks for more information.

[ Return to beginning of section ]

## Using My Sidebar

In addition to navigating the Web with Navigator, you can let the Web come to you by using My Sidebar.

My Sidebar is a customizable frame in your browser where you can keep items that you need to use all the time—the latest news and weather, your address book or Buddy List, stock quotes, a calendar—and many other options you can choose. My Sidebar presents these items to you in tabs that it continually updates.

Mozilla comes with some My Sidebar tabs already set up, but you can customize My Sidebar by adding, removing, and rearranging tabs. For details, see My Sidebar.

To view an item in My Sidebar, click its tab.

| If you don't see My Sidebar, it may be closed. Open it by clicking its handle. If the handle is missing, select View and then My Sidebar.

# Searching the Web

In this section: Fast Searches Advanced Search Mode Bookmarking Search Results Setting Search Preferences Using Internet Keywords Finding Related Pages Searching Within a Page Searching the Bookmarks or History List

## Fast Searches

There are three ways to search quickly: from the Location Bar, from My Sidebar, and from the Net Search page.

### Searching From the Location Bar

Searching for web pages on a particular topic is as easy as typing a question, or just a word or two, into the browser's Location Bar, as pictured below.

For example, if you want to find information about baby dolls:

1. Double-click in the Location Bar to select the current text.
2. Type the word "baby doll". Your typing replaces the current text.

Perform one of these steps:

- Click the Search button.
- Click "Search Netscape Search for "baby doll" at the bottom of the drop-down list in the Location Bar. (You default search engine may be different.)
  The default search engine you choose in Preferences is used. Search results for "baby doll" appear in both the browser window and in My Sidebar. Click the links to visit web pages about baby dolls.

After you perform a search, the results are saved in My Sidebar's Search tab until you do a new search. You don't have to click the Back button to retrieve the search results.

To save the results of a search, click "Bookmark this Search" in My Sidebar. To return to the list later, open the Bookmarks menu. You'll find the search results in a folder at the bottom of the Bookmarks menu.

Note: You can also use Internet Keywords to search from the Location Bar.

### Searching From My Sidebar

The My Sidebar Search tab lets you quickly search and bookmark your search results. For example, if you want to find information about toy cars:

1. If it is not already open, open My Sidebar by clicking its handle.
2. Click the Search tab.
3. Open the "using" drop-down list, and choose a search engine.
4. Type "toy car" in the search field.

## Using Internet Keywords

Internet Keywords work with the Location Bar to help you quickly find specific types of information. There are several ways to use Internet Keywords:

- Type a specific product, trademark, or company name and press Enter (Return on Mac OS), to go directly to a company's web site.
- Type certain verbs, such as "shop" or "quote," followed by the word you want to look up, to get specific information. For instance, "shop pets" takes you to a page with links to online pet stores.
- Type the name of a city or town followed by certain words such as "movies" or "restaurants," for local information. For instance, type "san francisco restaurants".

Hint: The most commonly used Internet Keywords are listed in the pull-down list to the left of the Location Bar. Click the triangle and choose from the list. To see a longer list of keywords, choose List of Keywords.

Important: To use Internet Keywords, you must press Enter on your keyboard (Return on Mac OS) instead of clicking the Search button. Pressing Enter activates the Internet Keyword feature; clicking Search initiates a search.

To see the difference, try this:

1. Type "apple imac" into the Location Bar and press Enter (Return). Apple Computer's iMac Web page appears.
2. Now type "apple imac" into the Location Bar and click Search. You see a list of links related to Apple Computer's iMac models.

If typing Internet Keywords into the Location Bar is not working for you, check your Smart Browsing preferences to be sure the Internet Keywords feature is enabled.

### Quick Stock Quotes

To see a recent stock quote for a company, type "quote" followed by the company's stock ticker symbol, and press Enter.

If you don't know a company's stock ticker symbol, type the company's name. The quote page will list all companies with similar names, and you can choose the one for which you want a quote.

## Finding Related Pages

Whenever you visit a web page, your browser generates a list of related pages for you to consider. The What's Related list is displayed in My Sidebar.

| If it is not already open, open My Sidebar by clicking its handle. If the handle is missing, select View and then My Sidebar.

Note: The What's Related list may be closed, so that only its tab is showing. To open it, click its tab. If the What's Related tab is not visible, you must add it to My Sidebar.

To visit one of the web pages in the What's Related list, double-click its link.

### Smart Browsing Preferences

If you prefer not to use What's Related or Internet Keywords, you can turn these features off.

1. Open the Edit menu and choose Preferences.
2. Under the Navigator category, click Smart Browsing. (If no subcategories are visible, double-click the category to expand the list.)
3. Under "What's Related Sidebar Tab," list any domains for which you do not want What's Related information, and then click Add. Domain names are the part of a URL that contains the name of an organization, business, or school—such as netscape.com or un.org.
4. Under Internet Keywords, deselect "Enable Internet Keywords."

What's Related works by gathering information on the browsing habits of a huge number of Internet users. If you do not wish What's Related information to be gathered in conjunction with your browsing, you can disable What's Related by turning off or removing the What's Related tab from My Sidebar. See Removing My Sidebar Tabs.

# Using Languages and International Content

In this section: Selecting Character Codings and Fonts Setting Language Preferences Finding International Web Content

## Selecting Character Codings and Fonts

If you browse, compose, or send and receive email in more than one language, you need to select the appropriate character codings and fonts.

A character coding method is the way a document or message has been converted to data to be used by your computer. All web documents and mail and news messages use a character coding method (also known as a character encoding or character set).

The character coding method for a document depends on its language. Some languages—such as most of the Western languages—share the same coding method. Others, such as Chinese, Japanese, and Russian, use different methods.

Your version of Mozilla is set to a default character coding appropriate for your region. However, if you use more than one language you may need to select appropriate character coding methods and designate the fonts you wish to use for your coding method.

To select character codings, begin from the Navigator window:

1. Open the View menu, choose Character Coding, and then choose More.
2. Choose a region from the top section of the submenu.
3. Choose a character coding within the region submenu. Repeat steps 1-3 for each character coding method you want.

The character coding methods you select are added to the Character Coding menu. If you have more than one coding method selected, the active one has a bullet (dot) next to it.

Mozilla can detect which character coding a document uses, and can display it correctly on your screen. To take advantage of this capability, begin from the Navigator window:

1. Open the View menu, choose Character Coding, and then choose Auto-Detect.
2. Choose one of the Auto-Detect options, or choose Auto-Detect Off from the submenu.

To make changes to your list of active character sets:

1. Open the View menu, choose Character Coding, and then choose Customize. You can see the Customize Coding dialog box.
2. Choose from the following procedures:
   - To add to the list of active character sets, choose a character set from the list on the left and click Add.
   - To remove a character set from the active list, choose a character set from the list on the right and click Remove.
   - To change the order in which the browser checks for character sets, highlight character sets in the list on the right, and use the arrow buttons to move the character sets up or down in the list.

To change the default fonts within a language group:

1. Open the Edit menu and choose Preferences.
2. Under the Appearance category, click Fonts. (If no subcategories are visible, double-click the category to expand the list.)
3. From the "Fonts for" drop-down list, choose a character coding method. For instance, to set default fonts for the Western character set, choose "Western."
4. Select whether proportional text should be serif (like Times Roman) or sansserif (like Arial). You can also specify what font size you want for proportional text. Proportional text varies in width.
5. (If available) Select a font for Serif, Sans-Serif, Cursive, and Fantasy.
6. Select the monospace font (like Courier) that you want to use for web pages. Monospace text is fixed in width, so each character or letter takes the same amount of space.

Many web page authors choose their own fonts and font sizes. You can use the author's font settings by selecting "Allow documents to use other fonts."

To adjust the readability of fonts, select from the drop-down list the dots per inch (dpi) for displaying Web pages. Select "Other" to open the Calibrate Resolution dialog box, which allows you to calibrate your resolution by measuring how long a line appears on your screen.

[ Return to beginning of section ]

## Setting Language Preferences

The language you use for Mozilla affects the text of buttons, dialog boxes, menus, tools, and other items. The functionality of these items remains the same.

To set your preferred language:

1. Open the Edit menu and choose Preferences.
2. Click on the Appearance category.
3. Use the "Choose your preferred language for Mozilla" drop-down list to select the language that you want to use in Mozilla.
4. Click OK.

   Note: You must restart Mozilla after you change your preferred language.

The content pack you use affects the home page, bookmarks, toolbar contents, My Sidebar, and other items.

To use a content pack:

1. Open the Edit menu and choose Preferences.
2. Under the Appearance category, click Content Packs. (If no subcategories are visible, double-click the category to expand the list.)
3. Under "Installed Content Packs" select a content pack.
4. Click OK.

   Note: You will have to need to restart Mozilla after you change to another content pack. To download more content packs for Mozilla, click "Download More".

Web pages are sometimes available in several languages. Mozilla presents pages in the language you prefer, if it is available. You can specify the languages you wish to see, in order of preference.

To set language preferences:

1. Open the Edit menu and choose Preferences.
2. Under the Navigator category, click Languages. (If no subcategories are visible, double-click the category to expand the list.)
3. Click Add. You see the Add Language dialog box.
4. Select a language and its code. If you wish to add a code not on the list, type the language and its code in the Others field (see note, below). If you want to reorder the languages in the list, select a language and click Move Up or Move Down.

# Improving Speed and Efficiency

In this section: Managing Different File Types Making Mozilla Your Default Browser Automatic Loading Changing Cache Settings Getting the Latest Software Automatically Using a Mouse Wheel Using Quick Launch

## Managing Different File Types

Navigator can handle many types of files. However, for some files, such as movies, Navigator launches a "helper" application that can handle the file, or it saves the file for you to view later.

The settings in the Helper Applications preferences panel tell Navigator which helper applications to use on your computer. You probably don't need to change them because they come preconfigured. Also, if Navigator doesn't know which helper application to use, it allows you to find helper applications within the download dialog box.

The download dialog box has these options:

- Open using: Mozilla opens the file using the default program in your system settings.
- Choose: Mozilla allows you to open the file using an application you choose.
- Save this file to Disk: Mozilla allows you to select a location to save the file.
- Always ask before opening this type of file: When this is selected, Mozilla opens the download dialog box when downloading a particular file type. You can reset these choices afterwards in preferences for Helper Applications.
- Advanced: Mozilla allows you to fine-tune how files are handled. See "To add a new helper application to the list" for details.

For experienced users to fine-tune the Helper Applications preferences:

1. Open the Edit menu and choose Preferences.
2. Under the Navigator category, click Helper Applications. (If no subcategories are visible, double-click the category to expand the list.)
3. Perform any of the following procedures:

   To add a new helper application to the list:

   1. Click New Type. You see the New type dialog box.
   2. Type a description of the type of files the application works with; for instance, "movies" or "sound files."
   3. Type the file extension (suffix) used by this file type. If this type of file uses more than one extension, type them all, separated by spaces.
   4. Type the MIME type. MIME types consist of two words separated by a slash. For instance, a TIFF image file's MIME type is "image/tiff".
      Note: When you download a file, Mozilla will show you the MIME type on the download dialog box.
   5. Click Choose, then select an application that handles files of this type.
   6. Click OK.

   To specify how Navigator should handle downloaded files:

   1. Select a file type from the list and click Edit.
   2. Choose a "Handled By" option to have downloaded files saved on your hard disk or opened in an application that you specify. Click Choose to specify the application.
   3. Select "Ask me before opening downloaded files of this type" if you want to be notified before downloading files that are handled by applications other than Navigator.
   4. Click OK.

   To remove an item from the list:

   1. Select a file type from the list and click Remove.
   2. Click OK.

2. Click the Advanced category.
3. To load pages faster, deselect one or all:
   - Enable Java: Allows Java applets (small programs that add functionality to pages) to run automatically.
   - Enable JavaScript for Navigator: Allows JavaScript (commands that add functionality to pages) to run automatically.
   - Enable JavaScript for Mail & Newsgroups: Allows JavaScript to run automatically for Mail & Newsgroups.

To save time typing your password when you use "anonymous" as your user ID for an FTP site, choose "Send this email address as anonymous FTP password." Choosing this option transmits your email address automatically when you log on to a public FTP (File Transfer Protocol) site. FTP sites are used for transferring files.

## Changing Cache Settings

Your computer stores copies of frequently accessed pages in the memory cache or disk cache. This way, the computer doesn't have to retrieve the page from the network each time you view it.

To set the size of the memory cache or to clear it (Windows and Unix only):

1. Open the Edit menu and click Preferences.
2. Under the Advanced category, click Cache. (If no subcategories are visible, double-click the category to expand the list.)
3. Enter a number in the Memory Cache field to specify the size of the memory cache. 1024K to 2000K is a good size. To clear the memory cache immediately, click Clear Memory Cache.

Important: A larger memory cache allows more data to be quickly retrieved. But unless you have a lot of extra memory on your computer, 1024K is sufficient.

To set the size of the disk cache or to clear it:

1. Open the Edit menu and choose Preferences.
2. Under the Advanced category, click Cache. (If no subcategories are visible, double-click the category to expand the list.)
3. Enter a number in the Disk Cache field to specify the size of the disk cache. 8000K on Windows is sufficient (5000K on Unix). To clear the disk cache immediately, click Clear Disk Cache.

Important: A larger disk cache allows more pages to be quickly retrieved, but more of your hard disk space is used.

When you quit Mozilla, it performs cache maintenance. If maintenance takes longer than you wish, try reducing the size of the disk cache.

To specify how often Navigator checks the network for page revisions (so that you don't keep "stale" pages in the cache too long):

1. Open the Edit menu and choose Preferences.
2. Under the Advanced category, click Cache. (If no subcategories are visible, double-click the category to expand the list.)
3. Choose from the following options:

- Every time I view the page: Select this if you want Mozilla to compare a web page to the cache every time you view it.
- Automatically: Select this if you want Mozilla to compare a web page to the cache when the page is determined by the server to have expired.
- Once per session: Select this if you want Mozilla to compare a web page to the cache once for each time you start Mozilla.
- Never: Select this if you do not want Mozilla to compare cached information to the network.

If pages that should be in the cache are taking longer to appear than they should, make sure the preference is not set to "Every time I view the page," because the verification requires a network connection that takes time.

To refresh a page at any time:

- Click the Reload button in the browser's navigation toolbar. The computer checks the network to make sure you have the latest version of the page.

To retrieve a fresh copy of a page regardless of what's in the cache:

- Hold down the Shift key (Option key on Mac OS) and click Reload.

## Using Quick Launch

Note: Quick Launch is available only on Windows installations of Mozilla.

Quick Launch shortens the time it takes for Mozilla to start. When Mozilla uses Quick Launch, the Mozilla logo icon is present in the taskbar (near the time). Double-clicking on this icon will quickly start Mozilla (if it isn't started already).

Tip: To quickly start components (such as Composer, Mail & Newsgroups, and the Address Book window), right-click the Mozilla logo icon and select the component in the pop-up menu.

When you installed Mozilla, you were given the option of enabling or disabling Quick Launch. If your computer is low in memory, or if you are have more then one profile, you can temporarily or permanently disable Quick Launch to conserve memory. If enabled, Quick Launch will start when the user starts Windows.

To temporarily disable Quick Launch until you start Mozilla again:

1. Close all open Mozilla windows, including Navigator, Mail & Newsgroups, and Composer. If you have unsaved information, you are asked if you want to save it.
2. Right-click on the Mozilla logo icon in the taskbar (near the time) and select "Exit Mozilla" from the pop-up menu.

To enable or disable Quick Launch in Mozilla:

1. Open the Edit menu and choose Preferences.
2. Click the Advanced category.
3. Select "Quick Launch" to enable Quick Launch, or deselect it to disable Quick Launch.
4. Click OK.

   Tip: To easily disable Quick Launch, right-click on the Mozilla logo in the taskbar (near the time) and select "Disable Quick Launch" in the pop-up menu.

# Proxies

In this section: Setting Proxy Values

This section explains how to work with proxies.

## Setting Proxy Values

Many organizations block access from the Internet to their networks. This prevents outside parties from gaining access to sensitive information. The protection is called a firewall.

If your organization has a firewall, the browser may need to go through a proxy server before connecting you to the Internet. The proxy server prevents outsiders from breaking into your organization's private network.

Before you start:

- If there's a proxy configuration file at your workplace, ask the system administrator for its URL.
- If there's no proxy configuration file, ask your system administrator for the names and port numbers of the servers running proxy software for each network service.

To set the browser to work with the proxy:

1. Open the Edit menu and choose Preferences.
2. Under the Advanced category, click Proxies. (If no subcategories are visible, double-click the category to expand the list.)
3. Select one of the following:
   - Direct connection to the Internet: Choose this if you don't have to go through a proxy.
   - Manual proxy configuration: Choose this if you don't have a proxy configuration file. Type the name or numeric IP address of the proxy server for HTTP and FTP. Type each proxy server's port number in the Port field.
   - Automatic proxy configuration URL: Choose this if you have a proxy configuration file. Type the file's URL in the field and click Reload.

(If you select Manual proxy configuration) In the "No Proxy for" field, type the names of any domains that you can connect to directly, bypassing the proxy. For example, if you type "netscape.com", then the proxy is bypassed each time you view a web page from netscape.com.

Domain names are the part of a URL that contains the name of an organization, business, or school—such as netscape.com or washington.org. If you use local host names without the domain name, list them the same way. Use commas to separate multiple host names. The wildcard character [*] cannot be used.
