After restarting my PC for windows updates, it refused to boot, and I ended up having to do a full reset. I've used a recovery tool to dig out the old appdata Firefox files, but am unable to reapply my old bookmarks. I have previously done it using a json file, some years ago. Reading up now, it seems I need the places.sqlite file. I have firefox closed, and remove the profile folder, only to replace it with the retrieved one, though that does not seem to do anything, nor am I able to restore my bookmarks, as there is no saved json file that I can find. I assume I am stupidly doing something wrong.
