Mode should fallback when accepted file type is not found (FF)53 replies [Last post]
If I understand modes correctly when an accepted file type is not found the player should fallback to the next mode.
If you visit this page with FF the mode order is Flash-HTML5-Download.
With Flash enabled it works.
With Flash disabled it does fallback to HTML5, but the player should at this point detect there are no supported file types, since the files listed are mp4 and not WebM, and subsequently fallback to Download.
So I think that there is an issue with the fallback feature for when a supported file type is not present and doesn't then attempt the next mode.
