Could you test in Firefox's Safe Mode? In its Safe 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 Safe Mode using either:

• "3-bar" menu button > "?" Help button > Restart with Add-ons Disabled
• (menu bar) Help menu > Restart with Add-ons Disabled

and OK the restart. A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

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 "Start in Safe Mode" (not Refresh).

Any improvement?

Oddly enough, yes, and no - lol. The Address bar still shows the Skytales addy - but it does take me to the video/page I was aiming for. So, I was aiming for this - https://www.thedodo.com/ and got this - https://www.skytales.org/notable-health-benefits-of-neem/

Now - address bar shows the skytales addy, but gave me the dodo video!

Thank you. Oddly- yes and no to the fix. I was aiming for - thedodo.com and I got https://www.skytales.org/notable-health-benefits-of-neem/ However- even though the address bar shows the skytales address, I did get the dodo video. Stangeness abounds.
