Guide on How to reduce the memory usage in Firefox?

Firefox 2.0 since its release had the niggling memory leak and no matter how many updates have been out to address this issue it still has that retard issue. A standard Firefox install without any extensions consumes around 80MB but soon after you add a few extensions you can see a noticeable drop in the performance. There are many guides out over the internet but i have made my own version that seems to work. It gono be a pretty comprehensive guide so you have a stick a little longer to learn the tricks.

First of all make sure you have the latest version of Firefox, presently If you don’t have which i doubt. You can download using the link below, if you are kind enough grab my referral link.

1. Extension and themes the main cause of memory leaks.

A standard install of Firefox doesn’t seems to show any memory leak issues. But after installing few extensions it seems to show the memory leak issues. Basically this issue occurs due to buggy, bloatware extensions. Also if you overloaded your Firefox with extensions, you can expect high memory usage. Same goes for themes, don’t install too many themes. To minimizes memory issues try testing each plugin one by one for few hours and check over their memory signature. As a result you can always find out the buggy ones and help yourself minimizing the high memory usage. You can even check this comprehensive list of buggy extensions and find out if one of your extension belongs here. Always keep your extensions updated this is another way to cope with the issue.

2) Start Firefox in Safe Mode

If one of your extensions is not in that list, boot Firefox into Safe Mode to disable all extensions and themes. You can do this by going to Start > Run, and entering:

firefox -safe-mode

A similiar looking box will appear .Now check Disable all add-ons
now click on Continue in Safe Mode. Now fire up your Windows task manager and compare the memory usage before and after disabling the extensions. Normally disabling extensions only drops of couples of MB of ram. But if you find some memory spikes this surely indicates some problems of either of the extensions or themes installed.


3) Plugins:

Another memory hogger are the plugins that are needed for open special media or application within Firefox, like Java chat, PDF reader, WMV, Quicktime etc. Here are some links from MozillaZine that offers some basic solutions to plugin related issues.

4) Clear your Download History
