I was having the "PRR_END_OF_FILE_ERROR" Secure Connection Error and after going through that whole list of fixes ending with me deleting my firefox account and creating a new one the issue is still happening on sites like youtube after trying to play a video for a bit so i disovered that the two default plugins were giving these messages: OpenH264 Video Codec provided by Cisco Systems, Inc. will be installed shortly", "Widevine Content Decryption Module provided by Google Inc. will be installed shortly." and wont install so at this point I think the final issue I need to solve to 100% fix things is to get these two plugins to finally install but I don't know how to force it to do that

https://support.mozilla.org/en-US/questions/1359657#answer-1463359 and updated to 95.0. . . . I finally found where the plugin "Widevine Content Decryption Module provided by Google Inc." was not updating to the newest version of December 1, 2021. Ver #4.10.2391.0

cor-el; Make sure you have the latest Widevine version. You can toggle DRM off/on to see if that makes Firefox (re)load DRM components.

You can possibly check the XHR requests in the Browser Console if this doesn't work.

You can try to disable DNS over HTTPS.

You can check the connection settings.

  • Settings -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":

it looks like the dns over https thing is the problem if i disable it everything works fine. is there a way to fix it so that i can keep the dns over https enabled or is it a problem that is currently happening with cloudflare. I also still need to figure out how to get Widevine Content Decryption Module provided by Google Inc. to install so I can avoid any future issues because of it
