@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 profile while the profile is enabled, the whole issue is fixed whereas apparmor still can take care on security. That goes along with what @mailing-m1 already posted in comment 13. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1627239 Title: Web pages not rendering with e10s enabled and AppArmor profile in enforce mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1627239/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
