1. I believe that it is wrong to post the whole of a reply as you have, 
immediate before the signature of the person to whose message, you are 
replying, as it makes it too easy for people to misconstrue, for 
example, in the above case, that what you posted, was posted by me.

2. "I would expect Firefox to offer to download the file or choose a 
viewer" - I believe that you can configure Firefox to apply a third 
party application, such as a viewer of video files, for dealing with 
particular file types/extensions.

3. "I would expect Firefox to offer to download the file or choose a 
viewer" - why do you not simply download and install one or some of the 
video downloader add-ons that are available for Firefox?

4. If you do not know how to do either 2 or 3, I suggest that you 
subscribe to, and, post a query to, https://groups.io/g/firefox-support
