Thunderbird will not open .MOV attachments.
Thunderbird will not open .MOV attachments. Will only allow the file to be saved. It DOES open MP4 attachments directly without saving.

I can't duplicate this on W10/TB 91: if I send a mov attachment to an account, it's received as usual, and right-clicking, Open, displays the dialog in the attached picture. Checking the 'Do this...' box saves the choice to Preferences. Check the message source (Ctrl+U) for the Content-Type header of the attachment. It should be video/quicktime.
