I have Windows XP and Firefox 52. Starting yesterday, I was no longer able to play videos in Youtube with either Flash or HTML5. Today I found out I can't play videos in Vimeo or Dailymotion either. How do I fix this?

Your system details shows no flash player.

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.

Flash Player Version: Version 26.0.0.137

Also, I think XP needs something from Microsoft. I called for more help.

Firefox relies on built-in OS support to play (MP4) media files via the HTML5 media player. On the Windows XP platform you do not have native support for playing MP4 files with the HTML5 media player.

You can try if the solution posted here to add support for playing MP4 files works for you.
