Hello, I had 2 open firefox windows on each of my monitors. I was doing work and at the end, I closed every window on my PC. When I came to the firefox windows I closed my "secondary" window first and it said "would you like to close 3 tabs" and I clicked yes. That is pretty normal, when you have 2 windows. Then I closed my "main" window the one that is always restoring when I open firefox and it also said "you're about to close 20 tabs". Once again, sometimes this happens, sometimes it doesn't, but it always knows to restore it, so to me it's normal. I put my pc to sleep and I the next morning I turn on the pc and it opens a blank homepage. I think nothing of it, so I go to try and restore it through the history and that doesn't work. I go online to look how to restore it and it says everything about backup on the profiles folder. I go there and it isn't showing the files that I had, just the ones that I used this morning. I try to change the firefox profile to see if that window is in another one it isn't. I had hopes that it wasn't erased because that morning when I opened a window and I had more than 1 tab it said to me "would you like to close 4 tabs" and that always happens when there is more than one window open. So in the end I abandoned to recover the tabs I just could do it from the history. My WHOLE history that I collected for the past 6 years is gone and all my cookies. I have Firefox Sync and it shows my history on my phone, but when I go to sync it, it still doesn't show. I need help with at least recovering all my history and cookies; Bonus points if you can try to recover my lost window. Thank you!
