Used to love this. I have autobackup set up after a round a long time ago of it losing all my tabs. I don't save every single backup for space. My oldest is currently from last June. I've been saving tabs for projects, work, etc and when I tried to save one today it simply wouldn't respond. The majority of my tabs are gone and the groups empty. I'm not sure when it happened; even my oldest backup only has a couple of additional tabs to add. A lot of the newer things I added aren't there. I've lost tons of stuff. With backups, it never occurred to me I needed to check to make sure things were still there to even be backed up; my bad, I guess, for not going through every folder making sure every single thing is still where it's supposed to be at least weekly. Everything is simply erased.
