Thank you for the reports. They are all different, which is frustrating in looking for a pattern.

Could you test in Firefox's Troubleshoot Mode? In that mode, Firefox temporarily deactivates the JavaScript compilers, extensions, hardware acceleration, and any optional userChrome.css/userContent.css files to help you assess whether any of these are causing the problem.

If Firefox is running:

You can restart Firefox in Troubleshoot Mode using either:

• "3-bar" menu button > Help > Troubleshoot Mode...
• (menu bar) Help menu > Troubleshoot Mode...

and OK the restart. A small dialog should appear. Click the Open button.

If Firefox is not running:

Hold down the Shift key when starting Firefox. (On Mac, hold down the option/alt key instead of the Shift key.) A small dialog should appear. Click the Open button.

Note: Don't use the Refresh without first reviewing this article to understand what will be deleted: Refresh Firefox - reset add-ons and settings.

Any improvement?
