If you want to increase the speed of your browsing with Firefox, follow 
these simple directions:

Open Firefox.
Type "about:config" in the adress bar (no quotation marks).
Find these options, double click each one and change to below values:

network.http.max-connections: 48

network.http.max-connections-per-server: 24

network.http.max-persistent-connections-per-proxy: 12

network.http.max-persistent-connections-per-server: 6

network.http.pipelining: true

network.http.pipelining.maxrequests: 32

network.http.proxy.pipelining: true

Lastly right-click anywhere and select New-> Integer. Name it 
"nglayout.initialpaint.delay" and set its value to "0". This value is 
the amount of time the browser waits before it acts on information it 
receives.

Close Firefox and enjoy the faster browsing.

Supercharged!
