THIS IS A VERY SIMPLE TRICK. NO SOFTWARE REQUIRED.
1. Type "about:config" into the address bar and hit enter. Scroll down and look for the following entries:
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. 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 recieves.
NOTE: this trick only works for broadband users not for dialup.
