My add-on and default profile have disappeared after I entered safe mode. The browser window restarted with a new interface with different settings and all my add-ons were gone. There reason why I tried out safe-mode was to restore my open tabs which were lost after firefox updates but still showing in history without the possibility to restore them. Currently, I have three profiles in about:profiles but non of them contains my add-ons data. They all appeared as if I am opening the browser for the first time. Inside the profiles file explore, there are 5 newly created profiles see attached screenshots. Things I did, Cleared cache, refreshed the profiles and restart the browser nothing works. What is going on. :(. This sucks. I had special add-ons which contained my valuable settings and now they are all gone.
