Got a popup from Mozilla in a new Window. Switched back to my normal firefox. When closing I got a "anonymous" question "do you want to leave this page". I couldn´t figure out what page was giving the warning (didn´t say anything i dialog titlebar!) so I had to say yes. Then I had to close the popup-window that still was open in the background. When opening FF again everything was gone: ALL tabs from including my fixed program tabs! No session was saved to restore. Hey, not nice! And now I can´t click "submit Feedback" on the sad-face feedback page. Hey, not nice! I can´t explain the problem in 140 characters and if you don´t want to know the details then you can´t fix it an then I don´t find any purpose in reporting problems. Hey, not nice! On the Sad-face page there is just a greyed out Submit Feedback button but no alternative link to report the problem from another page. Hey, not nice!
