Speed Up Firefox for DSL or Cable Connections
Trick to speed the page load with Firefox:
A) Type "about:config" into the address bar and hit return. Scroll and search for the these 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 speeds up the page loading.
B) Chage entries as follows: mark "network.http.pipelining" as "true" mark "network.http.proxy.pipelining" as "true" mark "network.http.pipelining.maxrequests" to 30. The value 30 means that firefox will make 30 requests at once,
C) right-click and select New> integer. Create the integer as "nglayout.initialpaint.delay" and put the value to "0". The number 0 is to avoid the delay that the browser waits before it acts on information it recieves.
D) now create another integer named " ui.submenuDelay" and set it to 0
there u go...

If you follow step by step you will notice a faster page load
