Speed up Firefox

If you have a high-speed (Cable, DSL, etc.) connection this change will give you a very noticeable speed increase for larger web pages. Inside the address bar on Firefox (where web page addresses/URLs go) type this and press enter: about:config
and then find: network.http.pipelining
network.http.proxy.pipelining
and set them both to "true". This adjusts the pipelining settings.
For more cool settings available in about: config, go here.)

Then find network.http.pipelining.maxrequests and set it to 8, as suggested by http://kb.mozillazine.org/Network.http.pipelining.maxrequests (though you can play with this number).

Finally, right-click anywhere (on any setting) and a menu will pop out: select 'new' and then 'integer'. Copy this (without the quotes): "nglayout.initialpaint.delay" and paste it in as the name, and then set the value to "0" (zero). This removes the render delay. You should experience a BIG speed increase!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
