Hi Rick, I don't recognize that one. What page has that message -- is it a built-in Firefox page like the new tab page, or is it a specific website?

Could you test in Firefox's Troubleshoot Mode? In that mode, Firefox temporarily deactivates extensions, hardware acceleration, any userChrome.css/userContent.css files, and some other advanced features to help you assess whether 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?

I thought it was only happening in Firefox, but realize now, it happens regardless of what program I'm in, so it may not be a specific Firefox problem. I will try the Firefox trouble shoot, maybe that will work. thanks.

I should have tried your proposed solution before I sent the last email. When I click restart, no box opens either before or after it restarts. The 3-bar says I'm in Troubleshoot mode. What am I doing wrong?

If multiple programs are affected, it's possible some part of Windows has died and you need to do a regular shutdown/restart of Windows.
