Just installed Chrome and Firefox, I'm using Edge since the Windows 11 install. All 3 browsers are working fine.
I turned everything off on windows defender and did reset to default, it removed all the rules from windows firewall, very clean, then chrome would not work anymore loading videos then I created a new firewall rule udp port 5353, that is the same rule microsoft edge uses and voila worked again, did the same thing to firefox and youtube videos still not loading hehe, everything else works, videos on facebook and other places no issues with firefox, only on youtube ehhe
Well on firefox there is a plugin called "Widevine Content Decryption Module provided by Google Inc.", not sure if that is the case why is not loading videos on youtube. The plugin will not download, have done the manual installation and after you install and close firefox, you check and says the plugin is not downloaded and then you have to do the manual installation and the same thing happens, firefox does not keep the settings saved once it is closed, everything is so strange hehe
The other plugin close to widevine is openh264 and no issue on that, it is downloaded every time without an issue. Firefox.exe can't reach google and download this plugin, xhr requests on developer mode says nothing.
