Issues with GLIB+Iceweasel+apt-get

I caused the bug but I would like to fix it without doing the amateur "fresh" install. HOW: I copied a bunch of commands and ran them. OS: Debian 8 When I run Iceweasel the following services crash the browser - gmail - facebook Additionally my browser crashes after I input words of a certain length into the search bar, the issue won't reproduce today and I haven't saved any logs.

espo@EVA-00:~$ sudo iceweasel

My Issue with apt-get is more straightforward.

espo@EVA-00:~$ sudo apt-get install vlc
