<i>duplicate of [/questions/1476458] thread</i> This happened too much, like 6 times when using firefox in this month. I dont want to shut the program because I got unsaved notes in it. I was listening to music and it just began to play it non stop. and it dont respond. please help, a million thanks! I try to restart network or suspend the process nothing works. If I could make firefox reopen to it's original state+ cookies; no site reloaded and get back my incogico it would be much appreaciated.
