These instructions include how to increase your browsing speed on Firefox (If you use Wyzo browse this blog for similar tweak).
First, in Firefox type, “about:config” into the address bar (and ignore any warnings!).
In the filter field, type “network” and scroll down to “network.http.pipelining” and set it to TRUE, and set “network.http.pipelining.maxrequests” from 4 to anything from 8 to 12.
This simple tweak one change could increase the page-load time by what felt like a factor of 50%.
