Firefox trick

Firefox is the fastest and very fast but there is a lot more we can do to make it faster..
Here what you have to do:

you type "about:config" at the URL and press enter, This will bring up the configuration “menu” where you can change the parameters of Firefox



Double Click on the following setting and put in the numbers below
**for the true / false booleans - they’ll change when you double click.

To make it easier, you can copy, for example : network.http.max-connections
then, paste it to "filter" on the screen.



Code:
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
nglayout.initialpaint.delay - 0 (if don't have, you right click somewhere at the screen then choose new->integer , and name it nglayout.initialpaint.delay, set it to "0"

After you finish all these, restart your firefox..and walaa..it become faster
