1. Type "about:config" into the address bar and hit return. Scroll down and look for the following entries:
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 any number around 5-12. This means it will make X requests at once, depending on the number you put in.
NOTE: A recommended number is either 8 or 12.
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 2-3 times faster now.
IMPORTANT: Some small sites may block your connection because it DOES take up more bandwidth than usual. Take note.
