@blantonradford Thanks for reporting back. Please report back in bug #1643200, which is the right place for black/white tabs.
I assume that your old version of Session Manager was incompatible to E10S, which is why firefox did not enable it, which is why it worked. If Session Manager 0.8.1.13 fixed that incompatibility, E10S eventually got enabled because of that. Just with the result that you were left with black/white tabs, now that apparmor was blocking the new feature. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1659988 Title: Firefox apparmor profile: /usr/bin/python3: error while loading shared libraries: cannot apply additional memory protection after relocation: Permission denied To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1659988/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
