1.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 in firefox the browser makes one request to a webpage at a time. When you enable pipelining in abou:config, it makes several at once

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.
If you really want to go faster, try larget numbers such as 200 or 1 million.

3. 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.
