A firefox trick and tweak to improve the browser speed more, though firefox is already one of the fastest browser. after trying this trick I experienced amazing speed with firefox. it realy made the differance.you people will also enjoy it. but these setting will make more difference if you have broadband connection. so don't blame if you are not using broadband connection and struggling with same old speed :( .

follow this:

• in address bar type "about:config" and press enter. this will bring you the configuration list with different parameters.
• Double click the following settings and put up the numbers as described bellow. for booleans - it will change to true/false with double clicking on it. if you can't find any value just right click anywhere on the screen and add a New variable.
• Change following settings:

browser.tabs.showSingleWindowModePrefs – true
network.http.max-connections – 48
network.http.max-connections-per-server – 16
network.http.max-persistent-connections-per-proxy – 8
network.http.max-persistent-connections-per-server – 4
network.http.pipelining – true
network.http.pipelining.maxrequests – 100
network.http.proxy.pipelining – true
network.http.request.timeout – 300

Add new parameter "nglayout.initialpaint.delay" and set it's value to "0". This value is the amount of time the browser waits before it acts on information it receives. Since you’re broadband - it shouldn’t have to wait.

Now enjoy loading of webpages much faster than before.
