I just came across this when trying to find out why the latest Nvidia drivers have screwed up video platback on my PC

Here's something for broadband people that will really speed FireFox up:

1.Type about:config into the address bar and hit return. Scroll down and look for the following entries: network.http.pipelining network.http.proxy.pipelining network.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.

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!

I have no idea if this works but I'll be trying it tonight hopefully.
