I tried these and my firefox loads pages almost instantly now. Very useful IMO.
To get started, open your Firefox web browser. In the address/location bar type [about:config] and then press your Enter key. (NOTE: DON’T TYPE THE BRACKETS.)
Tweak #1:
In the Filter bar type [network.http.pipelining]. Then, double-click on this line under Preference Name in order to change the value from false to true.
Tweak #2:
In the Filter bar type [network.http.pipelining.maxrequests]. Then, double-click on this line under Preference Name and change the value from 4 to a higher number anywhere from 10 to 30. I set mine to 30.
Tweak #3:
In the Filter bar type [network.http.proxy.pipelining]. Then, double-click on this line under Preference Name in order to change the value from false to true.
Tweak #4:
In the Filter bar type [network.dns.disableIPv6]. Then, double-click on this line under Preference Name in order to change the value from false to true.
Tweak #5:
In the Filter bar type [plugin.expose_full_path]. Then, double-click on this line under Preference Name in order to change the value from false to true.
Tweak #6:
In the Filter bar type [network.protocol-handler.external.ms-help]. Now, you are going to create a new Preference Name with an Integer Value. To do this, right-click on this line under Preference Name and select New, then Integer. In the New Integer value box type in [nglayout.initialpaint.delay] and click OK. Then in the Enter Integer value box type [0] (that’s a zero) and click OK.
Tweak #7:
In the Filter bar again type [network.protocol-handler.external.ms-help]. Now, you are going to create another new Preference Name with an Integer Value. To do this, right-click on this line under Preference Name and select New, then Integer. In the New Integer value box type in [content.notify.backoffcount] and click OK. Then in the Enter Integer value box type [5] and click OK.
Tweak #8:
In the Filter bar again type [network.protocol-handler.external.ms-help]. Now, you are going to create another new Preference Name with an Integer Value. To do this, right-click on this line under Preference Name and select New, then Integer. In the New Integer value box type in [ui.submenuDelay] and click OK. Then in the Enter Integer value box type [0] (that’s a zero) and click OK.
Now, close your web browser and restart it. You’ll see how much faster web pages are loading.

If you don't use too many Firefox plugins and you just want speed, try Minefield (the beta for the next full release of Firefox).
Quite a lot of the plugins I use and love are incompatible (including the English spell checker) so I've stopped using it but it has one of the fastest Javascript engines around, which means performance-wise it was great. I found it quite stable for browsing web sites and forums, so that's not a concern.
