When I'm trying to play a video on a site (file is .mp4), it will ask me what to do with the file i.e. Save it or Open it with VLC instead of just playing it in the browser. I can see thumbnail of the video so I don't think it's a plugin problem (like with the Flash plugin on this page https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_flash-plugin). I just did a clean install of Windows 10 Pro N, updated to 1909 and installed everything fresh (even the Media Feature Pack for Windows 10 N (November 2019). Was previously on Windows 7 with FF and never had this happen to me in 10 years... How to simply play videos in the browser without having to "download" them first and then play them with VLC ? I've searched online for more than 1 hour and even had to register here just to ask this... PLEASE HELP !!!

I HAVE FOUND THE WORKAROUND : Problem was that i was on Windows 10 PRO N Version, and apparently it was lacking some features...

Solution : go to settings > apps > Optional features > add a feature > Media feature pack and download it.
