Firefox, without doubt is one of the most preferred browser for lot of users. But it does have its drawback. At times, it is notorious for consuming lot of memory which slow down the computer performance. Some problems can be attributed to memory leak which may have resulted from poor coding. From time to time, Firefox did release updates which took care of these problems. Here are some steps which can be tried if you suspect Firefox consuming too much memory.

Check Memory consumed by Firefox

  • Press Ctrl+ Alt+ Del. Click Task Manager. (You can also right click on Task bar and open Task Manager)
  • Check the memory consumed by Firefox.

It is natural for Firefox to consume up to 400MB – 600MB memory with minimum 5 website window open. Also, more the time Firefox is open, more the chances for consuming more memory.

How to resolve Firefox using too much memory

  • Check with less number of Tabs open

Too many tabs opened can lead to more memory consumption. So, reduce the number of tabs opened in Firefox. Check if that reduce total memory consumed by Firefox.

  • Restart Firefox

Close Firefox completely and then open it. Continue to work on Firefox. Don’t open too many tabs. Watch if the memory consumption is going up. If the memory consumption is going up, there might be a memory leak from Firefox software or from add-ons installed in Firefox.

  • Run Firefox without any add-on

Click on Help Tab, Select Restart with Add-Ons Disabled. Now work on Firefox normally for some time and check memory consumption. If the memory consumption is not shooting up, the problem might be with an add-on installed in Firefox. Disable one add-on at a time and then check memory consumption. Using this method, find the culprit and then remove the Add-On.

Note: In latest version Firefox 26, all plug-ins are set to click to play which means the plug-ins are not loaded by default. When a website requires a particular Add-On, it prompts for permission and you have to give permission.

There is also an add-on approved by Firefox for checking add-on memory usage. It can give clear details on memory consumed by each add-on.

  • Keep Firefox up to date

Check if Firefox is up to date. Click on the Help Tab and then click on About Firefox. It automatically checks if you have the latest version.

Keeping browser updated is essential as the frequently released updates might have fix for memory leak issues.

  • Re-install Firefox

Uninstall and Re-install Firefox. When a software is used on a computer for a long period of time, there are chance of file corruption from frequent system changes and virus attacks. Re-installing Firefox from scratch fix most of these problems.
