Hello

After updating firefox I got logged out of firefox, after logging back in no profile data is available. I lost all the saved passwords, setting, browsing history, all of it. I lost access to website's because of it. Tried copying data from 'profiles' folder but it does not work. Never had problem like this ever and I'm considering changing browser for good. It should have never happen, like wtf is this?!
