The majority of the information comes from this excellent thread over at the MozillaZine Forum.

First, install ChromEdit or ChromEdit Plus (for Firefox 2) extension. It make it easier to edit user files.

Now, run Firefox, go to Tools > Edit User Files. For Firefox 2, Tools > ChromEdit Plus > ChromEdit

Click user.js tab.

Insert the following texts based on your PC speed and internet connection.

Common to all configurations

These are the settings that seem to be common to all configuration files regardless of connection speed or computer speed with a couple of additions - plugin paths can be found with about:plugins and the bookmark menu delay is turned off.
CODE
user_pref("network.http.pipelining", true);
user_pref("network.http.proxy.pipelining", true);
user_pref("network.http.pipelining.maxrequests", 8);
user_pref("content.notify.backoffcount", 5);
user_pref("plugin.expose_full_path", true);
user_pref("ui.submenuDelay", 0);


Fast Computer Fast Connection
CODE
user_pref("content.interrupt.parsing", true);
user_pref("content.max.tokenizing.time", 2250000);
user_pref("content.notify.interval", 750000);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 750000);
user_pref("nglayout.initialpaint.delay", 0);
user_pref("network.http.max-connections", 48);
user_pref("network.http.max-connections-per-server", 16);
user_pref("network.http.max-persistent-connections-per-proxy", 16);
user_pref("network.http.max-persistent-connections-per-server", 8);
user_pref("browser.cache.memory.capacity", 65536);


A couple settings of note - Firefox is allocated 4096 KB of memory by default and in this configuration we give it roughly 65MB as denoted by the last line. This can be changed according to what is used.

Fast Computer, Slower Connection

This configuration is more suited to people without ultra fast connections. We are not talking about dial up connections but slower DSL / Cable connections.
CODE
user_pref("content.max.tokenizing.time", 2250000);
user_pref("content.notify.interval", 750000);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 750000);
user_pref("network.http.max-connections", 48);
user_pref("network.http.max-connections-per-server", 16);
user_pref("network.http.max-persistent-connections-per-proxy", 16);
user_pref("network.http.max-persistent-connections-per-server", 8);
user_pref("nglayout.initialpaint.delay", 0);
user_pref("browser.cache.memory.capacity", 65536);


Fast Computer, Slow Connection
CODE
user_pref("browser.xul.error_pages.enabled", true);
user_pref("content.interrupt.parsing", true);
user_pref("content.max.tokenizing.time", 3000000);
user_pref("content.maxtextrun", 8191);
user_pref("content.notify.interval", 750000);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 750000);
user_pref("network.http.max-connections", 32);
user_pref("network.http.max-connections-per-server", 8);
user_pref("network.http.max-persistent-connections-per-proxy", 8);
user_pref("network.http.max-persistent-connections-per-server", 4);
user_pref("nglayout.initialpaint.delay", 0);
user_pref("browser.cache.memory.capacity", 65536);


Slow Computer, Fast Connection
CODE
user_pref("content.max.tokenizing.time", 3000000);
user_pref("content.notify.backoffcount", 5);
user_pref("content.notify.interval", 1000000);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 1000000);
user_pref("content.maxtextrun", 4095);
user_pref("nglayout.initialpaint.delay", 1000);
user_pref("network.http.max-connections", 48);
user_pref("network.http.max-connections-per-server", 16);
user_pref("network.http.max-persistent-connections-per-proxy", 16);
user_pref("network.http.max-persistent-connections-per-server", 8);
user_pref("dom.disable_window_status_change", true);


One of the changes made for this particular configuration is the final line where the status bar is disabled for changing web pages to save processor time.

Slow Computer, Slow Connection

We have entered the doldrums of the dial-up user

CODE
user_pref("content.max.tokenizing.time", 2250000);
user_pref("content.notify.interval", 750000);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 750000);
user_pref("nglayout.initialpaint.delay", 750);
user_pref("network.http.max-connections", 32);
user_pref("network.http.max-connections-per-server", 8);
user_pref("network.http.max-persistent-connections-per-proxy", 8);
user_pref("network.http.max-persistent-connections-per-server", 4);
user_pref("dom.disable_window_status_change", true);


Click Save and restart Firefox

Happy surfing..

-------------------------------------------------------

another speed tweak..

Open Firefox.. type about:config

look for network.dns.disableIPv6

Double click to toggle it to 'true' and then restart Firefox. You should notice a speed increase, page to page.

This tweak disabe IPv6 in Firefox, because most if not all of the web is still using IPv4. IPv4 and v6 are internet protocols... how the data is transferred... v4 is the standard now and v6 is slowly being implemented around the world... it wont come into full swing until 2008-2010 sadly... it's a huge infrastructure change, but the benefits will be great.

It seems that chrome edit doesn't support firefox 1.0 sad.gif

temporary solution:

type about:config in addressbar
find app.extensions.version aand change value to 0.9
now all 0.9 extension will works on PR release.

you downloaded, but did you install it ?

Tools> Extensions
then drag the extension you have download into that small window

the restart your firefox, not computer

Tools> Edit User Files
then you will see your user.js section there

hope this will help
