We have recently seen a lot of issues reported on Mac with Session Restore.
I don't know yet what is causing them.


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, so you will have to create them again (make a note or bookmark them).

Hi Mozilla-Firefox team! Question? I noticed that my downloads weren't being scanned any longer and the Download Arrow caught my eye. Plus This Now "Firefox 20: is Slow and Freezes with my AOL account also! How do I revert back to "Firefox 16?" If the above download arrow didn't catch my eye" I wouldn't have even noticed that I was switched to Firefox 20!" I really do not like it-sorry.Thank you for what ever help you could give me on this issue.Michael.
