Make Firefox Load Pages Faster

Steps

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
2. 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.

3. Alter the entries as follows:
4. Set "network.http.pipelining" to "true" by double-clicking it.
5. Set "network.http.proxy.pipelining" to "true" by double-clicking it.
6. Set "network.http.pipelining.maxrequests" to 8 by double-clicking it. This means it will make 8 requests at once. There is no point setting it higher then 8 as it is capped at 8 max. [The default value for this setting is 4]
7. 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 receives.
8. If you're using a broadband connection you'll load pages MUCH faster now!

Tips

* Alternately, you could install Fasterfox, an extension which does some of this automatically, and makes tuning easier.
* For more information on Firefox Tuning see the Firefox Tuning sticky thread at the independent MozillaZine forums.
* Also the MozillaZine Knowledge Base on Network entries in about:config and what they do.
* You can also run Firefox in your RAM (no reading from the HD means faster Firefox) by following this article.
* If you have problems like slow down, pages not loading or images loading weird, just undo the tweaks in about:config
* You can also do this in the Internet explorer browser, In opera an alternative is: go to opera:config and go to performance. Then change the max number of connections to 32

Warnings
Take note that doing this can actually make certain pages run SLOWER.
