Yep- firefox is a speed demon. Watch it load those web pages. Hear that supersonic boom? It runs rings 
around Opera and Internet Explorer. Especially Internet Explorer. There are times, however, that Firefox loses its flame. Know why? All those extensions hobble the poor thang. If you want to regain that just-installed feeling, unload the uneeded extensions. Then follow up with the following browser optimizations:
First, execute the about:config page by typing about:config in the location bar. In the window that pops up, insinuate the following modifications:
Change network.http.max-connections-per-server to 32 – Standard is 15. Increasing it boosts the number of connections made to a single server. You’ll notice a speed blast when browsing during simultaneous downloads at rapidshare (you dirty pirate you!)
Change network.http.pipelining to true – Pipelining allows multiple requests to be sent to a web server before any responses are accepted. Firefox jumps with improved browsing speed if you’re on a lethargic connection.
Change network.http.max-connections to 96 – You increase the total number of HTTP connections Firefox can make to a web server. Most connect at only 30, but if you have sufficient bandwidth this increases the speed of loading of multiple-tab bookmarks.
Change network.http.pipelining.maxrequests to 16 – Anything about pipeling increases data flow. This particular option specifies the maximum number of requests to make to a server at once. Going to 8 will speed up your requests to a server. There’s a catch. You incur a delay penalty should one of the requests fail.
Ramp network.http.max-persistent-connections-per-server to 8 – Boosting this setting from 6 to 8 explodes performance as you sift through multiple pages of a site. I tried 12- wow, what speed! But some instability sets in.
Implement these minor tweaks right now. Then Restart your Firefox. You’ll feel like your browser just chugged some crack!
