So... No replies... Evidently this isn't the place to go for help with Firefox. I don't want to have to use a different browser, but these delays while editing are seriously aggravating.

Can anyone recommend a place where a person can get help with a Firefox problem?

Hello! Try reinstalling the browser! Have a nice day!

Thanks.

I think it's time to start using a different browser. It seems I have encountered a problem that cannot be fixed.

I would try a new profile. If it works, you can copy data from the old profile but you will have to reinstall add-ons (except plug-ins).

Thanks Terry!

I think I have isolated the source of the problem. It seems to be Facebook and the version of Windows I'm using. When I close the Facebook tab, the problem goes away. My guess is there may be processes that monitor my activities that take a lot of resources. I don't have the problem with other computers that are running Windows 11--only this one computer. For the time being, I am using Remote Desktop to use Facebook on another computer as a workaround. The computer with the problem is participating in the Windows Insider Program at the beta level.
