1. Type “about:config” into the address bar and hit return. 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 reallyspeeds up page loading.

2. Alter the entries as follows:

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.

3. 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 recieves
