The videos where you are getting the error on may actually be HTML5 and not using Flash Player.
You may not have Windows Vista updated with things like the Platform Update Supplement for Vista. https://support.mozilla.org/en-US/kb/fix-video-audio-problems-firefox-windows

The "video format or mime type not supported" message is always about the HTML5 media player. Firefox isn't able to play any of the media formats that the website is offering. This can be caused by failing native OS support for playing some media types, because Firefox relies on native support. The Web Console ("3-bar" menu button or Tools -> Web Developer) usually shows what content this is about.
