Wow! this Works!
Apparently Firefox is scaled for dial-up users and someone has found a way to adjust the pipelining to allow for more simultaneous connections and generally faster speeds.
Type “about:config” into the address bar and hit return. Scroll down and look for the following entries: network.http.pipelining, network.http.proxy.pipelining, network.http.pipelining.maxrequests.
Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading.
Set “network.http.pipelining” to “true”
Set “network.http.proxy.pipelining” to “true”
Set “network.http.pipelining.maxrequests” to some number like 30. This means it will make 30 requests at once.
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.
Try it – do you see a speed increase?
