Firefox minimizes unexpectedly

Firefox 16.0.1 minimizes randomly at times. I cannot really say exactly when. Usually after opening a site on a new tab, but mostly when opening multiple tabs from library items. It would start loading them and then library would reappear in the front as firefox minimizes by itself. Anyone else has noticed this?

Hello lascetic

check it in Safe Mode, select "Start in Safe Mode" and see if this happen again, if not see: Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems


thank you

Please mark "Solved" the answer that really solve the problem, to help others with a similar problem.

@ideato Unfortunately it's difficult to reproduce it because it happens kind of randomly, or I haven't figured out the pattern yet. So it would be hard to test it in safe mode. Thank you.

@cor-el. I have tried the Places Maintenance Add-on but didn't help. At the moment and as the issue is not very frequent, I prefer not to delete my history, so I haven't gone into removing the places.sqlite file. If other users have noticed a similar issue it may be a bug with the newer ff versions rather than a corrupted places.sqlite. Thank you.

I have the same problem on Windows 8. When page is loaded firefox and all opened applications are minimizing.
