This bug report documents an incompatibility between the version of
Thunderbird distributed with Ubuntu 18.04 and the version of VLC. One or
the other must be changed so that a video attachment opened by
Thunderbird is accessible to the user's default video player, VLC.
** Changed in:
Matthew, thank you for properly identifying the responsible component of

This is not a Thunderbird, VLC or snapd problem. This is an Ubuntu 18.04

Sebastien, this is not so much a snapd issue as it is an Ubuntu 18.04

center."

When I changed my default video player from Totem to VLC, Thunderbird
