I just upgraded to Firefox 9.0 - After first run of install, it reopened 3 pinned tabs, and one normal tab. Yet with only the few tabs open it was very laggy. So I opened taskmanager, and holycow! Firefox was using over 1,000,000k of memory. Screenshot: http://screensnapr.com/v/EV5ePx.jpg

I exit firefox, and then relaunched it - its still laggy! I'm getting key delays just trying to type this message.

Can anyone tell me how to fix this? Or downgrade back to 8.0 without loosing my Bookmarks/Passowords/Form History/etc ?

Do those App tabs have session history (i.e. enabled Back and Forward buttons)?

See:

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).


Create a new profile as a test to check if your current profile is causing the problems.

See "Basic Troubleshooting: Make a new profile":

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.

If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.
