upgrade renders firefox unusable

[Hadmut Danisch]

Hi,

I just apt-upgraded a 16.04 machine to the latest packages, which rendered firefox unusable. The firefox gui appears, but it does not show contents of webpages, refuses a login to an unencrypted (still secure because tunneled) webpage and blasts trillions of messages like

 [ 691.871185] audit: type=1400 audit(1485603229.158:2983): apparmor="DENIED" operation="mknod" profile="/usr/lib/firefox/firefox{,*[^s][^h]}" name="/dev/shm/org.chromium.fHVuSZ" pid=6325 comm=57656220436F6E74656E74 requested_mask="c" denied_mask="c" fsuid=1000 ouid=1000

into the log. Looks like wrong or outdated apparmor settings keep firefox from running properly.

There's more trouble with firefox. See the attached screenshot of the lower left corner of the window when trying to watch help messages

Status changed to 'Confirmed' because the bug affects multiple users.

I think this might be at least related to https://bugzilla.mozilla.org/show_bug.cgi?id=1334778.

[Hadmut Danisch (hadmut)]

Yup, looks related.

Firefox downloads pages and interpretes them (otherwise it could not complain about a password automatically filled into a form on an unencrypted web site, so it must have parsed the form), but displays just empty pages.

And indeed, trouble came with upgrade from firefox 50 to 51.

[Hunter Nichols (hnichols1995)]

Same problem! The point update 50.0.1 doesn't seem to solve it. Pages load fine in Chromium
