I don't know why but all of my browsing history disappeared a few days ago from my desktop firefox. I'm not sure but i was away a few days and when i came back I might have updated firefox, so it was recent. Already checked the profiles folders to see if it created a new profile or something. There's another profile, but the history file does not contain anything. I checked firefox on my android and I think my history is still there, but since i cannot filter im not sure. At least it is syncing with desktop. It already synchronized both ways but still no luck. What can I do?
