Torbutton addon prohibits saving media to storage

I edited the following in about:config

media.mediasource.mp4.enabled => false media.mp4.enabled => false

But this did not yield the expected behavior of saving the file to my Download folder. Instead the browser began saving a temp file in ./Download without notifying me and without even an entry in the download manager.

After playing around I discovered that if I disabled the Torbutton addon I would get the expected behavior of asking me to download an mp4 file when clicking on a direct link to one, e.g. http://www.moo.you/123.mp4

This is observed with Tor Browser for Android alpha-60.2.1 and the included Torbutton 2.1 installed from F-Droid.
