Solution 9: Switching Internet Access

Hi, I tried every suggestion and nothing works. Today I updated firefox to v94 and the issue persists. On other laptop, it works perfectly. I uninstalled firefox, deleted all related files and registries and installed again, but it didn't solve the issue. I don't know what to do anymore.

If you have Windows 10 N or KN then you may not have the Media Feature Pack installed. https://support.mozilla.org/en-US/kb/fix-video-audio-problems-firefox-windows
