Does Firefox support .mp4 video?
I find "AAC and H.264/MPEG-4 AVC are patented audio/video compression formats. They can be viewed in Firefox using built-in OS libraries (so neither Mozilla nor you need to pay a fee) if embedded in the MP4 container format (.mp4, .m4a, .m4p, .m4b, .m4r, .m4v file types)."
But when I create an HTML page with the following HTML5 code:
<!DOCTYPE html> <html> <body> </body> This is a test of video. <video src="C:/MyVideoFile.mp4" controls> </video> </html>
I get the error "No video with supported format and MIME type found". Does Firefox in fact support .mp4 video? If so, what changes do I need to make in the HTML?

After further experimentation, the error is due to the path in src. It should be either
<video src="file://C:/MyVideoFile.mp4" controls>
OR
<video src="MyVideoFile.mp4" controls>
if the .mp4 is in the same directory as the HTML file (other relative paths are possible)Read this answer in context 👍 0

See if this helps: Separate Security Issue: Update your Flash Player or remove it using these links; Uninstall Flash Player | Windows {web link} Uninstall Flash Player | Mac {web link}
Note: Windows users should download the ActiveX for Internet Explorer. and the plugin for Plugin-based browsers (like Firefox).
Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the ActiveX.
