I found this little gem on Forevergeek.com. If you a nice fast
broadband connection, this power-user tweak will instruct Firefox to
make multiple connections so it can download more pages at once.
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
If you’re using a broadband connection you’ll load pages MUCH faster now!
