Working at a project, had approx 20 to 30 tabs open for that and left it over night to continue today. The comp seems made a general update and restarting today seems Mozilla had upgraded too and appears with a specific mask (something new for me) as it wants by all means to enter a profile name finally to start working, i did, but having badly to recognize that all searched and open tabs are closed and deleted even from Chronik so that a week work just vanish .... I am absolutely angry about that .... at least update could offer and warning about to close and safe tabs as the update is going to delete them all.... aaaaarghhhhh
