Wont start after add-on update

Have FFP 3.1 installed and clicked to launch, the add-on updater asked me if I wanted to install updates for tor, better gmail and no-script (and maybe download -helper) they seemed to update ok but then FF wouldnt launch, just a message with something along the lines of "there has been a crash, would you like to quit or retry, and would you like to report this?"

the report fails and a retry fails only thing that works is quiting. Am using an old 2.15 install currently.

the report contents are:

BuildID: 2008070208

This report also contains technical information about the state of the application when it crashed.

Have tryed a reinstall over the old 2.15 install and this seems to be working but the addon updates arnt found...
