This is the last current version of Firefox that works with XP/VISTA https://ftp.mozilla.org/pub/firefox/releases/52.9.0esr/ Please pick 32 or 64 bit ( I think your 32 but you would know best) Pick your language if in the US it is US-EN

I would think your lucky playing anything as your Video Card Drivers are a mess. Please uninstall and reinstall them. adapterDescription: Intel(R) G965 Express Chipset Family driverDate: 7-21-2006 https://www.intel.com/content/www/us/en/support/detect.html

It is x-player you would need to search for minimum requirements. Technology is passing you.

Thanks again for your response. Whats is x-player ? thanks

You appear to be running a 52.0b9 Beta version.

Why aren't you using the last 52.9.0 ESR version for your OS?

thanks again. Sorry about that i have now installed 52.9.0 ESR. Still the same. Some vids will play but some won't . Thanks

Firefox relies on built-in OS support to play 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.

Thanks again, i did what it said in the link you supplied bit Primetime is not showing in my Plugins. Thanks.

You are going to have to Google x-player embedded and just x-player minimum requirements.

IF as suggested you can install VLC Video Lan and it will play almost anything. You Right Click URL's and stick URL's into VLC

Or the same with HPC-HCx64 discussed in URL

If you need Codecs for other stand alone players use K-Lite

what is x-player?

Strange that this only happened in the last month.
