Viewing Your Home Page

When you start Firefox, you will see your home page. By default,
you will see Firefox's home page.


Tips:


* To display more web content on the screen, you can use Full Screen mode.
Full Screen mode condenses the Firefox's Toolbars into one small
toolbar. To enable Full Screen mode, simply select
View > Full Screen or press
F11.

* To go to your home page quickly, press AltOpt+Home.

Moving to Another Page

You can move to a new web page by typing in its Internet address or URL
into the Location Bar. URLs normally begin with "http://" followed
by one or more names that identify the address. One example is
"http://www.mozilla.org/".



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 EnterReturn.



Tip: To quickly select the URL of the Location Bar, press
CtrlCmd+L.




Don't know a URL? Try typing something specific to the page
you want to visit, e.g. a name, into the Location Bar and hit EnterReturn.
This will take you to the top result in Google for that term.


Clicking a Link

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



1. Move the mouse 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 link's page, status
messages will appear at the bottom of the window.



Retracing Your Steps

There are several ways to revisit pages:



* To go back or forward one page, click the Back or
Forward button.

* 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 recently visited; to return to a page, choose it from the list.

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



* To choose from pages you've visited during the current session, open the
History 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 History menu and choose Show in Sidebar. You will see the
History Sidebar. The History Sidebar displays a list of folders.
Clicking the folders displays subfolders or titles of web pages.
You can click a page's title to view that page.



Stopping and Reloading

If a page is loading too slowly or you no longer wish to view a page,
click the Stop button.


To reload the current page or to get the most up-to-date version, click
the Reload button or press CtrlCmd+R.


Tabbed Browsing

When you visit more than one web page at a time, you can use Tabbed
Browsing to navigate the Web faster and easier.


Tabbed Browsing lets you open tabs, each displaying a web page, within a
single Firefox window. You don't have to have several windows open
to visit several different web pages. This frees up space on your desktop.
You can open, close, and reload web pages conveniently in one place without
having to switch to another window.


For more info, see Tabbed Browsing.


Using the Sidebar

The Sidebar is an area on the left side of the screen that you can use for
viewing bookmarks or history. Extensions may add new ways to use the Sidebar
as well.


To view an item in the Sidebar, select View >
Sidebar. From there you can select the Sidebar tab you want.
