Redirect Search Results
You can control where you see your 
search results. Type about:config into your location bar and find 
"browser.search.openintab", then double click to make it "true." Now 
when you use the search bar, your results will pop up in a separate tab 
instead of taking you away from your current page. 
Disable Window Resizing
 
 Web pages that resize windows drive some people up the wall. To fix 
that, go to Tools > Options, and open the Content tab. Click on the 
Advanced button next to "Enable JavaScript," then deselect the check box
 that allows scripts to "Move or resize existing windows." 
Choose a Tab
 
 As with IE, Ctrl+Tab will let you cycle through open tabs in Firefox. 
But if you want to go to a specific tab without using the mouse, use the
 Ctrl key and the number of the tab's position—Ctrl+1, for example, will
 open the first tab, Ctrl+2 the second, and so on. 
Browse Without a Mouse
 
 Tired of using the mouse? Ctrl+L will move you to Firefox's location 
bar, while Ctrl+K will move you to the search bar. (When you're there, 
hold Ctrl and use the up or down arrow keys to toggle the default search
 engine.) 
Open multiple sites at startup
  If you want
 to open multiple Web sites when you start Firefox, go to Tools > 
Options. Under the Startup section on the Main tab, you'll see the Home 
Page field. Enter the sites you want to open in this manner:
www.computershopper.com | www.collegebuyingguide.com.
www.computershopper.com | www.collegebuyingguide.com.
Mousing Around
 
 Your mouse gives you more browsing control than you might think. If you
 have a scroll wheel button, clicking it on a hyperlink will open it up 
in a new tab, while clicking it on a tab will close it. If you hold down
 the Shift key while scrolling, you can move backward or forward through
 your browsing history. 
Quickly Cross-reference
  Ever
 found something in an online article you instantly wanted more 
information about? Search for that information easily by highlighting 
the text, dragging it to the search bar, and pressing Enter. Firefox 
will search for that text automatically. 
Delete Inaccurate URLs
 
 If you've ever mistyped a Web site's address and then seen your mistake
 pop up whenever you retype the site's name, just highlight the site in 
the history and press Shift+Delete to get rid of it for good. 
Stay Stealthy
 
 If you don't want sites to know where you're coming from, type 
about:config into the location bar and then find the 
network.http.sendRefererHeader record. Double click on it, and change 
the "2" value to "0" to prevent Web sites from seeing your referrer 
information. 
Get More Viewing Space
  Want to maximize
 the Web-site view in your browser window? Then make your icons smaller.
 Just go to View > Toolbars > Customize and check the box next to 
"Use Small Icons." 
Quick URL Fill-in
  If you type a 
site's address without the usual ".com" or "www" and press Ctrl+Enter, 
Firefox will fill in the rest of the URL for you. 
Give Your Bookmarks Keywords
 
 To assign a keyword to a bookmark, simply right-click on it and select 
Properties. Write a word in the keyword field, and now when you type the
 word into the location bar, you'll automatically go to that site. 
Curb Firefox's RAM Appetite
 
 Firefox was once famous for how light it was on system resources. With 
each new update, however, it seems be become a bigger and bigger memory 
hog. Rein Firefox in a little by limiting the amount of memory it uses. 
Type about:config in the address bar and locate 
"browser.cache.disk.capacity." Normally, it's set to "50000," but you 
can lower that number if you find Firefox is using too much system 
memory. 
Cleaner Google File Searches
  Searching for 
multimedia files on Google can result in a lot of spammy results. An 
effective—if clunky—way to minimize getting such results is to type 
intitle:"index.of"(xxx|yyy)zzzz -html -htm -php into the search bar, 
where "xxx|yyy" are the types of files you want to find (such as 
"mp3|avi") and "zzzz" being the name of the files you want to find.
