This is about the HTML5 media player and not about a plugin like Shockwave Flash. It is possible that the website has changed from using a Flash based player (object tag) to the HTML5 media player (video tag).

Does the Web Console ("3-bar" menu button or Tools -> Web Developer) show more information about what file types are offered by the website?

When I get that notice, I just download the clip for later.

thanks . but it's a live feed or stream or whatever it's called ( i'm a real dummy here , sorry ) . also , when i encountered this problem , i went to Chrome directly and it could b played there with no problem . Thus , that's what i'm doing now , using Chrome to play that link ; yet , i'd like to know if there's any way i can solve it here in FireFox .

thank you so much !

If it is a stream (or a file with stream URIs) and not a playable file then you probably can't download and save it.
