@coeur-noir: Are you installing firefox to /opt/ as recommended or using it local in your user account?

Can you run sudo dmesg | grep apparmor and add the information here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2046844 Title: AppArmor user namespace creation restrictions cause many applications to crash with SIGTRAP To manage notifications about this bug go to: https://bugs.launchpad.net/apparmor/+bug/2046844/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
