I-Firefox Isithangami Sokwesekwa

Hello, I'm having issues with Google Widevine CDM on Amazon Prime Video, Spotify but also some websites using HTML5. YouTube videos work correctly.

I've checked all topics in standard Firefox support, but did not find solution.

It looks like Google Widevine CDM is not working correctly, but it appears as active and actual version in browser settings. I'm not sure, if this is somehow related, but recently I migrated from Windows 7 to Win 10 doing upgrade, not fresh install (not sure though, if on Win 7 it was working, or not. I wasn't using Prime or Spotify while on Win 7). Today I tried to reinstall the browser, so I have fresh settings right now, but still the same issue. Will appreciate any support.

Regards, Marcin

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

I previously thought this was a Udemy bug, but then I tried playing other DRM protected videos on 2x on both Firefox and Chrome to compare..... and Yes, audio(specially speech) crackles in video on playback on 2x. Reference DRM video : https://bitmovin.com/demos/drm Try playing this in 2x speed and observe the voice crackle. Does not occur on Chrome and Edge
