Mozilla Firefox is a graphical web browser developed by the Mozilla Corporation. Started as a fork of the browser component (Navigator) of the Mozilla Application Suite, Firefox has replaced the Mozilla Suite as the flagship product of the Mozilla project, stewarded by the Mozilla Foundation and a large community of external contributors.

Mozilla Firefox is a cross-platform browser, providing support for various versions of Microsoft Windows, Mac OS X, and Linux. Although not officially released for certain operating systems, the freely available source code works for many other operating systems, including FreeBSD,OS/2, Solaris, SkyOS, BeOS and more recently, Windows XP Professional x64 Edition.

Some more Tweaks

Enable the spellchecker for inputfields and textareas (default is textareas only)

layout.spellcheckDefault=2

Open lastfm://-links directly in amarok

network.protocol-handler.app.lastfm=amarok
network.protocol-handler.external.lastfm=true
Firefox Memory Leak Fix

Open a new tab. Type “about:config” without quotes into the address bar and hit enter/click Go.

Right-click anywhere, select New, then Integer. In the dialog prompt that appears, type:

browser.cache.memory.capacity

Click OK. Another dialog prompt will appear. This is where you decide how much memory to allocate to Firefox. This depends on how much RAM your computer has, but generally you don’t want to allocate too little (under 8MB), but if you allocate too much, you might as well not do this. A good recommended setting is 16MB. If you want 16MB, enter this value into the dialog prompt:

16384

(Why 16384 instead of 16000? Because computers use base-12 counting. Thus 16 megabytes = 16384 bytes. Likewise, if you want to double that and allocate 32MB, you’d enter 32768.)

Click OK to close the dialog box, then close all instances of Firefox and restart. If your Firefox still uses the same amount of memory, give it a few minutes and it should slowly clear up. If that fails, try a system reboot.

Now your Firefox will now be 3 - 30 times faster in loading pages.

  2. JonathanEllis says:

    Hi Miles,
    Thats because your filter is still selecting plugin.expose_full_path. Just clear the filter and you will see that the values you created are indeed there.

  3. DirtChief says:

    hmmmm, would be nice to know what the actual variables are standing for instead of all the pictures showing the same dialog over and over.

  11. it didn’t work. i’ve followed it one by one, why did it not work? pls, help me, pls, reply on my email

  12. isecore says:

    No, no, no. You should NOT follow this guide.

    Most of these tweaks have no effect at all (other than producing a kind of placebo effect) and others have bad effects for other people.

    For example, the HTTP-pipelining and maxrequests will unnecessarily add load on webservers without delivering content faster to you. Reducing the paintdelay is equally stupid, why would you want to render a page that isn’t fully loaded?

    The default settings for all of these settings are perfectly fine. Do not apply guides like this without knowing what or why you’re doing. Several benchmarks have shown that these tweaks have zero effect on speed, it just creates the illusion of added speed.
