Ubuntu 22 LTS, Firefox 131.0.3 (64-bit). My machine crashed last night, but when I booted it this morning to start figuring out what's wrong all my windows/tabs came up. (I have at least 6 windows (for organization of my) hundreds of tabs.) After 6 or so reboots (testing various usb device plug-in configurations) I'm finally done, but now only have 1 blank firefox window. I created an account for syncing so I wouldn't have to redo all that when I upgrade OS periodically; however, I didn't think this would happen, so I didn't sync before this. I would REALLY like to get my windows/tabs back in the configuration they were. Under 'manage history' there's an import/backup option, with restore; under that, it shows Yesterdays Date with 563 items, but clicking on 'restore' for that tells me it will replace my bookmarks file... And I don't know how to retrieve the previously synced data, having only used it in the (presumed) other direction. Any clues welcome!
