I've also had the same problem. I tested it with a few extensions and the error happened with all of them, so it seems to be an issue with the start of a gnome session. It happens mostly with guest sessions, but I've also seen it happen in normal sessions occasionally.
I'm also using Ubuntu Gnome 16.04 and lightdm. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1713513 Title: notification for extensions keep reapearing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1713513/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
