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 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.
If you're using a broadband connection you'll load pages MUCH faster now!
You have to close your browser after you make the changes. When you start it back up they will be in effect.
