Probably because your Vista machine doesn't have the media Microsoft API used by Firefox to play MP4. Vista is outdated.
Or Firefox doesn't supply adequate means to play videos. Why do computer folks think we should go out and buy new systems all the time? (whatever "API" means; I looked it up, by why speak in geekese?)
Please check that you have installed the Windows Media Pack from Microsoft. You can find instructions on what to do there: https://support.mozilla.org/en-US/kb/fix-video-audio-problems-firefox-windows Download the vista one; restart Firefox and you should be good to go
I have windows media pack 1, according to the label on my computer. The update available at that link would not work; apparently I need windows media pack 2. It odes not seem to be available; where is it? Thanks.
You need to follow the instructions here https://support.microsoft.com/en-nz/help/13858/windows-vista-service-pack-2-install to install SP2 first.
Chris - I can't seem to edit Sumo for some reason. Can you add that link into the article for Vista as a note for people with out SP2?
