faster firefox

to speed up firefox - here's some ideas...

1. type about:config in the address bar and hit return. then filter to network.prefetch-next. double click it so it says 'false'.
2. right click on the about:config page and select new -> boolean. name it config.trim_on_minimize and make sure the value is set to 'true'.
   
3. on the about:config page, filter to network.http.pipelining. double click it so it says 'true', then double click on network.http.pipelining.maxrequests and enter a higher number like 40. set network.http.proxy.pipelining to 'true', too.
4. lastly, right click anywhere and select new -> integer. name it nglayout.initialpaint.delay and set its value to “0″.

here and here are where I last read these, and explain them a bit more.
