Ok, I looked a bit, and it appears Firefox is trying to use the GDK-Mir backend, but I'm guessing the GDK-Mir backend is not mature enough yet (?), so the app bails.
Definitely not an Xmir issue as Xmir is not even trying to be used in this case. ** No longer affects: xorg-server (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to upstart-app-launch in Ubuntu. https://bugs.launchpad.net/bugs/1660450 Title: Firefox crashes unity8 zesty Status in Canonical System Image: New Status in upstart-app-launch package in Ubuntu: New Bug description: I believe this is a different bug than bug 1627311 using a fresh zesty install, logging into unity8 deb session I installed libertine manager Since FF is installed as part of the original image - it shows up automagically in the app drawer.
