Firefox will not play videos from any site, including YouTube, Twitter plays in home screen but does not play in full screen mode, FoxNews or any site. I hear audio but there is no video. Firefox automatically updated Friday May 12 2023 and I don't know if that update had a glitch. I tried reinstalling firefox and it still didn't work. I cleared all history, cookies, cache, etc and still does not work.

please help, thanks

What security software are you running? If you're running Windows Pro, try this option. https://www.howtogeek.com/399290/how-to-use-windows-10s-new-sandbox-to-safely-test-apps/

I figured it out, problem solved. It was a setting in Firefox. Not sure if it was a default setting after the update but it was under settings/general/performance. Uncheck both boxes and video works fine now. Thanks for the help.
