Firefox has reset entirely. All of my profiles, bookmarks and saved passwords have disappeared; only history from this session appears. When I look at "Sync" I see the tabs from one of the profiles in the "Tabs from other devices"... it looks like Firefox thinks I have signed in from a new device, but I haven't. The "tabs from other devices" lists the tabs from one profile under the correct device name. I am hoping all of the profiles, bookmarks, passwords etc are in there still. How do I "reclaim" these profiles on my laptop? Where is this information stored so that I can access it?
