Here is a simple tweak that boost your browsing speed with Firefox. You can see significant improvement in speed with this tweak.

1. First of all, 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.

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 ”30”
This means it will make 30 requests at once.

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.
