You do not have support to play H.264 MP4 files and also can't play WebM with VP9, but the latter is likely because for your Firefox 43 version. You should normally have support in your Vista operating system to play MP4 files.

You can check these support articles:

i prefer no upgrade the service pack

Why not? What do you have against that upgrade?

SP2 for Vista was released about 8 years ago, so it's not like some new, untested software.

No, websites decide how to serve their content, and the trend is definitely toward built-in players rather than plugins. If you want to to grab the content and use the player of your choice, you should look at extensions and downloaders.

Maybe ask at a Windows oriented forum if there is a solution for these service pack related issues.

here my plugins : http://i.imgur.com/q2dKPfj.jpg the only extension i have is the kaspersky protection from my antivirus

Why is the internal OpenH264 codec set to Never Activate? Try enabling it by setting it to Always Activate. It cannot be set to Ask to Activate, but it’s safe and most likely required. While at it, do the same for the Content Decryption module. You could even uninstall Flash at this point, even if it was just for testing, and only reinstall it for websites that require it. Speaking of, you also disabled Flash, so how do you expect H264 playback to work?

Firefox does not prevent H264 playback for me when disabling both add-ons, so you might need to add the Platform Update Supplement for Windows Vista as suggested above in the Fix video and audio playback problems on Firefox for Windows article. The other system may already have that installed, so you could check for it being present.

Also, I would really try to get a Windows 7 update for your OS. Vista is old, slow, insecure and prone to new issues. You may be one of the few still using it. ;) There is no point running it as long as possible, since you can expect more websites to break. And that’s regardless of Flash - most people uninstall it anyway simply because it is no longer needed. And of course, Firefox 43 is not as safe as current versions. The same goes for uninstalled Service Packs - if there is an issue installing it, chances are you have more issues in the OS, and you will experience more of them.
