Firefox 2.x and excessive memory consumption


I usually have a lot of tabs open in Firefox while I work. I’ve noticed (as have many others) excessive memory consumption by the browser at times. Right now firefox.exe is using 121,484K with only 9 tabs open. I rebooted first thing this morning, and I’ve had Firefox running for only about four hours.

Most of the information I’ve found says the problem has to do with misbehaving Add-ons, extensions or themes. I’m only running four Add-ons, and decided to uninstall all but my del.icio.us Buttons and Google Browser Sync. Unfortunately, the problem persisted even after a reboot.

I did some more searching and found this thread that suggests loading this image to see if your browser memory consumption goes through the roof. Mine did. I read further down the thread and found a problematic add-on is indeed Google Browser Sync.

Check out this list of problematic extensions to see if any of your favorite add-ons are listed. If none of your extensions are listed, try the suggestions found on the Standard Diagnostic for Firefox and the causes for Firefox Hangs.

You can also try the Leak Monitor extension to help determine what is the cause of your Firefox memory leak. PCtipsbox.com has four tips on handling Firefox memory usage as well.
