I'd like to share this tweaks that was taken from PC Magazines awhile back.
How to do the TWEAKS:
Open your FIREFOX browser and type "about:config" into the address bar and hit Enter. A large listing of the browser's internal configuration options will come up. Scroll down to change 3 important browser config options:
"network.http.pipelining" change from "FALSE" to "TRUE" by double clicking
"network.http.proxy.pipelining" change from "FALSE" to "TRUE"
"network.http.pipelining.maxrequests" change from "4" to "30"
After changing the 3 browser config options then you've just upgraded FIREFOX to a new browsing speed.
I did it and made a big difference in SPEEEED....TRY IT FOR YOURSELF ****
