firefox version 90.0.2
Ever since version 90.0.1, now using 90.0.2, the mouse has become very sluggish/jerky, even in settings pages. I have no extensions or addons installed and am using the system theme. Troubleshoot mode works fine and refreshing firefox does not help. This is on Windows 7 Ultimate.

Troubleshoot mode works fine
Are you saying the problem is gone?
Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes), any userChrome.css/userContent.css files, and some other advanced features to help you assess whether these are causing the problem. If the problem goes away, that tells us one thing. If it does not, that tells us something else.
Use these links to create a new profile. Use this new profile as is. Is the problem still there?
Type about:profiles<enter> in the address bar.
The new profile did not fix the problem. Is there a way to keep firefox in troubleshoot mode until fixed?
I called for more help.
Make sure all software, including the mouse, is up to date.
Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.
You will need to restart Firefox for this to take effect so save all work first (e.g., mail you are composing, online documents you're editing, etc.,) and then perform these steps:
- Click the menu button and select Options (Windows) or Preferences (Mac, Linux).
- Select the General panel.
- Under Performance, uncheck Use recommended performance settings. Additional settings will be displayed.
- Uncheck Use hardware acceleration when available.
- Close Firefox completely and then restart Firefox to see if the problem persists.

If the problem is resolved, you should check for updates for your graphics driver by following the steps mentioned in these Knowledge base articles:
This did not fix the problem.
I have been using troubleshoot mode since I can't fix the problem, however now that version 92.0.0 is installed, troubleshoot mode no longer fixes the problem. What has changed in troubleshoot mode for version 92?
