This morning Firefox failed to restore my session, but I know the process to restore it session manually. See this link and post similar screenshot of your sessionstore-backups folder.

I read your explanation in the link you posted.

I see that it's a real P.I.T.A.

I'm going back to Chrome and uninstalling Firefox.

Yeah, I have no idea how to manually restore a session in Chrome, because i can't recall a time not being able to restore my windows. This has been a long time issue with Firefox. You can mark this as resolved and have a nice day.

I never asked you how to restore history/sessions/tabs in Chrome because I never had this problem with Chrome. I stated that I was moving back to Chrome and uninstalling Firefox. If this is a known problem, then perhaps Mozilla should take a look at fixing it before they lose even more users. This issue is NOT resolved, nor does it look like it ever will be.
