Enjoy & Watch Your Speed!
Or If Not Try This One Too!
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 some number like 30. This means it will make 30 requests at once.
3. Lastly right-click anywhere in the "aboug:config" page 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.
4. Restart Firefox
If you're using a broadband connection you'll load pages 2-3 times faster now.
