Speed Up Firefox web browser

Sponsored Link
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.

I am providing some Very Useful Tips to speedup your Firefox.

In your location bar, type about:config

Once it Opens You should see similar to the following screen

In the filter bar type network.http.pipelining

Normally it says " false " under value field , Double click it so it becomes " true ".

Once you finished this you should see the following screen.

Tip2

In the filter bar again and type network.http.pipelining.maxrequests

Once you finished this you should see the following screen.

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.

  1. Hey the reason the last tip with the memory leak doesn’t work is because the WRONG VALUES are listed, as in they’re way too high. I imagine this is because Firefox actually sees the memory capacity in kilobytes and not bits so adjust the values accordingly (copy pasted from http://kb.mozillazine.org/Browser.cache.memory.capacity):

    Physical RAM Memory Cache (in KB)
    32 MB 2048
    64 MB 4096
    128 MB 8192
    256 MB 14336
    512 MB 22528
    1 GB 32768
    2 GB 45056
    4 GB 59392
    8 GB 75776

  2. so does this really work or not, because it looks like it can get screwed up and then the web browser will not work at all.

    what is the simplest check to see how fast your pages load, and then decide for yourself if going faster is really necessary?

  3. duh!! you guys just don’t know how to follow instructions or maybe you don’t understand basic instruction

    i’m using it now and my mozilla became faster

  6. Hi, I have followed all the above steps but my problem hasn’t been solved, i m using HP mini with windows 7 starter 1 GB RAM,
    my problem is just the slow switching over multiple tabs, each time I go to another tab it takes a while (sluggish), or u can say the ‘click’ on the tab takes time to happen, the rest firefox is working perfect in speed.
    Don’t know how to solve it, followed all these steps, still having same problem.
    Second problem is how to stop the automatic ‘Get add-ons’ which can be seen in Tools>Add-ons>Get add-ons
    Can anyone help pls?

  7. wooooooooow it really works for me even without tweaks billion of thanx for saving my time i test youtube running like water

  8. Thanks, worked perfectly for me, one thing you left out was to switch the network.protocol-handler.external.ms-help to “true.” Saw that the screen shot had a t instead of an f, so worked out for me.

  9. My Firefox seems to be running slightly faster but is still much slower than Google Chrome. Chrome, on the other hand, often shows “not available” on sites that Firefox is able to access so I sort of try to get to where I want to be by using a mix of the two, still a bit frustrating.

  12. How do I go from here? I followed everything fine until I reached “Some more Tweaks” where the instruction was to enable the spellchecker for inputfields and textareas (default is textareas only) layout.spellcheckDefault=2.

    It says “Open lastfm://-links directly in amarok”, now I have no idea what amarok is and where to find it or how to implement the rest of the tweaks:

    network.protocol-handler.app.lastfm=amarok
    network.protocol-handler.external.lastfm=true
