A fraternity brother sent me this tip. It may be old news, but for me, it worked great to speed up the already fast Firefox browser if you have broadband.
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.
Sites that loaded slowly in the past pop up quickly now.

Lead Mozilla QA wrangler Asa Dotzler wrote about these tweaks on his blog. Granted, enabling HTTP pipelining can help, but setting the initial paint delay to zero “may get you some content on the screen faster, but it’s worth noting that it will dramatically slow down the time it takes the entire page to display.” :-/
Ok Alex so 0 is bad for initial paint delay, but what is a good number?

zero seems to work great on my end.
Kenny: I’d leave the initial paint delay at the default value — I think the Mozilla developers knew what they’re doing in this case :).
Here’s another for you:
Open Firefox ..type about:config in the address bar and press enter.
Type network.dns in the filter box at the top of the page, two results should remain.
Double click on network.dns.disableIPv6 to change its value to “True”
Restart Firefox. You should notice a speed increase, page to page.
Enjoy!
Alex: Ok, I go back to default on that one and see if I notice a difference when I get home tonight. 🙂
bhell13: I’ll give that a go when I get home tonight.
