during the last two weeks a new fenomenon with firefox occured that becomes ever more frequent: popups that, if closed, will close the application, too. some are empty, some show frames. they are not reproduceable. three screenshots:
accessing a german forum
, trying to read norwegian news
and, finally, trying to post about this failure in linuxquestions.org
. when this failure occurs, the computer will slow down significantly.

upgrade might always be a solution, but i don't always find it too easy. e.g. importing bookmarks in firefox will always need some work afterwards.
