Unfortunately, "usr.bin.firefox" of 14.04 has a different structure when
compared to 16.04. So the patch fails.

I uploaded a patch named "VERSION 4" at

for 14.04. Would you like to retry?

@christoph-thomas I did not propose to disable the apparmor profile. I
just disabled it to demonstrate that the issue is fully related to the
apparmor profile provided by ubuntu and not related to FF upstream.
Later on, I uploaded a patch which fixes the profile itself. With the
patch applied to
The patch of @Thomas Mayer only applies cleanly to LTS 16.04, while I
run 14.04.
@Sami Jaktholm:
I had to add another line to your proposal in comment #3 in
/etc/apparmor.d/local/usr.bin.firefox to get it running:
/dev/shm/org.chromium.* rw,
/run/shm/org.chromium.* rw,
Not only "/dev" but
I do not think the proposed patch by @Thomas Mayer
https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1659988/+attachment/4809979/+files/usr.bin.firefox.patch
completely disables apparmor for firefox, but allows access to certain
aspects of the system. Those access rights seem to be necessary
@Thomas Mayer 1659988 proposes to disable appamor for firefox. This
works, but is a very poor solution in terms of security. I prefer the
solution proposed by Sami Jaktholm (sjakthol) on 2016-09-25 in his 3'rd
post.

A patch which might fix this issue, too, is available at 1659988.

Everyone affected, please give it a try and report back.
I think it should fix your issues too.
@Maintainers: This issue might duplicate
@mikecaines-gmail This issue is apparmor related, whereas FF's apparmor
profile is part of the firefox package as demonstrated here (first file
is the apparmor profile):
http://packages.ubuntu.com/xenial/amd64/firefox/filelist
That said, this issue needs to be fixed in the firefox package and
Just ran into this today, make sure to grant Firefox rw access to
/dev/shm/org.chromium.*, I first tried just with write access and it wasn't
enough.
Is there something I can do to propose a fix? It's just the single line from
#3.

If you are running in complain mode you could look at the audit log and
see what AppArmor complains about when you are browsing the web with
e10s enabled. If you see AppArmor complaining about Firefox accessing
some specific paths, those might be causing he issues you are seeing.

Hi Sami!
The proposed workaround does not work for me. Only setting apparmor to
complain mode allows shm access and renders websites... Any hints?
Thanks

Hi,
this bug should not be reported against the apparmor package. The profile
/etc/apparmor.d/usr.bin.firefox belongs to the firefox package. Also I did not
face the problem on all machines, investigating this I found machines where is

As a workaround, you can run the following commands to allow Firefox to
access shared memory:
echo "/dev/shm/org.chromium.* rw," | sudo tee -a
/etc/apparmor.d/local/usr.bin.firefox
sudo apparmor_parser -r /etc/apparmor.d/usr.bin.firefox
That should make e10s work again with AppArmor
