Two days ago the Mozilla home page suddenly disappeared with all the windows open, on various websites and all my favorites. I tried in every way to recover it but it wasn't possible. Until a year ago I used Safari and the only thing I could do was import all the old favorites onto my new Mozilla home page, which however were not the same ones I used now. All the sites that I had stored in my favorites with passwords disappeared, even the email ones, I no longer recognized anything I had, as if I had never used Firefox. Has the same thing happened to anyone?
