How to Optimize Firefox Speed ( check this out wrks great)

Firefox is in my opinion the best browser ever made until now. It includes:
-improved tabbed browsing
-pop up blocking
-integrated Goggle search
-enhanced privacy controls
-built-in phishing protection
-online spell checking
-lots of themes, interfaces, and extensions/addons

Mozilla Firefox officially supports:
-Microsoft Windows
-Linux
-Mac OS X

Unofficial Support:
-Free BSD
-OS/2
-Solaris
-SkyOS
-BeOS
-XP Professional x64 Edition

Mozilla’s Firefox is good. With a little minor “tweaking”, however, you can make Firefox perform up to 40% faster for page transfers.

Here’s How:

1. Open the Firefox “config” page: click into the Firefox address location bar, and type about:config, press Enter.
2. The “Config” file will appear in the Firefox browser as a page with hundreds of lines of code in it. Now, we start by enabling some advanced tabbed options:
3. Locate the line browser.tabs.showSingleWindowModePrefs . (tip: press “b” on your keyboard to quick scroll).
4. Double click on browser.tabs.showSingleWindowModePrefs . This will set its toggle to “true”. Now your advanced and enhanced tabbing should be set.
   

1. Note: in Firefox version 1.5, the command line is singlewindow.openintabs.
2. Next: we will increase the “pipeline” RAM ability for Firefox to accomodate more packet transfer. In the same config document, scroll down to the line that says network.http.pipelining . Double click this line to set it to “true”.
3. Lastly, we will increase the maximum pipeline requests to 100. Find the line that says network.http.pipelining.maxrequests. Double click on it, and a dialog box will pop up. Change the setting from 4 to 100.
4. No need to save this file. Simply close and restart Firefox, and you should see an immediate 10% to 40% increase in web page transfer speed, and faster opening of your tabbed windows! Enjoy!
