Hack Your Broadband Connection.
Basically after getting to the hidden config settings you set the browser to request more data that it usually does.
Step 1:
Type "about:config" into the address bar and hit enter. Scroll down and look for the following entries:
network.http.pipelining
network.http.proxy.pipelining n
etwork.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.

Step 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.

Step 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.
