How to Improve the speed of Firefox 3 :

We all know Firefox is a memory hog. To speed things up greatly, do the following:

• Open Firefox and in the address bar type about:config.
• Click on “I’ll be careful, I promise
• Use the search bar above to look for network.http.pipelining and double click on it to set it’s value to True.
• Create a new boolean value named network.http.pipelining.firstrequest and set that to True, as well.
• Find network.http.pipelining.maxrequests, double click on it, and change its value to 8
• Look for network.http.proxy.pipelining and set it to True.
• Create two new integers named nglayout.initialpaint.delay and content.notify.interval, set them to 0.
• Restart your browser.

All done. You should feel the browser is 5x more responsive than before while navigating websites.
