2. Tweak /etc/fstab to have /home mounted noexec
3. snap install firefox
4. Reboot (mount -o remount,noexec /home doesn't seem to trigger the problem)
5. Try to watch a video needing the Widevine plugin

Actual results:

If /home is mounted noexec, then is there a more appropriate place for a user to store executables?
Is the purpose of a noexec /home to prevent user-installed executables, like the widevine plugin, from running?

@karlt, I don't mind having to mount /home with exec if that's needed. It took me a long time figuring out that noexec the source of the plugin crash. In other words, if a warning/error could be displayed, it's be much appreciated, please!
