firefox crashes when closing a tab sometimes
Last modified: 2018-04-11 09:51:13 EDT
Description of problem:
My firefox crashes sometimes when I try to close a tab while I have another one

starting it and continuing the session. I was able to get a backtrace at which
you might want to have a look at.
