Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

This is a crash in flash or similar, which we don't really have influence on. But actually apport isn't supposed to create crash reports for this in the first place -- can you please attach /var/log/apport.log and copy&paste the output of

   cat /etc/apport/blacklist.d/firefox

? Thanks!

Nevermind, we found it. firefox ships a /etc/apport/blacklist.d/firefox file which should *always* at least contain /usr/lib/firefox/plugin-container . We don't want crash reports for that as that's non-Ubuntu software which we don't control anyway. Apparently this was just turned back on in, but in 15.10 and earlier releases that file is completely empty.

Dropping /usr/lib/firefox/firefox might be desirable if you want crash reports for firefox itself, but please always keep plugin-container blacklisted.
