Well, if you are streaming a video or a media file in Firefox browser then suddenly a cross sign appears then you’ve encountered the no video with supported format and mime type found an error. This error is quite frequent to users as Firefox uses flash player like Adobe Flash Player.

What is no video with supported format and mime type found an error?

This error is a browser error that shows up when your flash player doesn’t work correctly. Since Firefox has followed the trend and removed all plug-ins from the browser as HTML5 is in use, therefore this error is quite frequent.

  • Corrupted cache and cookies– Every browser stores cookies and cache for different websites. If they get corrupted then this error can occur.
  • Corrupted Plug-ins– Since many websites use plug-ins to run media files in the browser, corrupted plug-ins can cause this error too.
