The closest I've come to a solution was disabling hardware acceleration. That totally solved the issue for ONE day. Now it's just back to the same old thing. There is even a lag in typing this question. UGH!

I've already tried reinstalling Firefox, but it did not take care of the issue.

You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox profile folder that store session data.

Delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox profile folder.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them if possible).
