Google translate translates comment 19 to "Thomas Mayer (thomas303),
after adding the owner /dev/shm/org.chromium.* rw in the patch and
Apparmor profile for Firefox Firefox earned. Thank you. But this is a
crutch, an update on the issue as there was no and no. Employees of
Canonical - Students who do not test software security."


There's no reason to believe that the package maintainers lowered
security by NOT applying necessary changes to the new requirements of FF
49+. It's rather the other way round: Not widening the apparmor profile
to the new requirements of FF is pretty conservative in terms of
security. It's just that apparmor blocking requirements of FF renders it
broken now - be it because of that conservative approach or because of
not testing at all. I agree, that should and could have been tested in
the first place, namely before releasing new major versions of FF.

Of course, the FF package needs to be updated to fix this issue for
average users. I'm not the maintainer of the FF package, which basically
means that I don't have permission to do that myself.

I guess that you can speed up Canonical's integration of the patch into
the official package by testing it and reporting back if it works. The
reason for that is that package maintainers hopefully become more
confident that the patch really fixes exactly this issue as long as
multiple users report exactly that, independently of each other.
