Firefox 技術支援討論區

Each of the threads below is someone reporting the same problem (which I also have), with the same timing. Suddenly on 21 April 2021 all (?) major streaming sites started to give "The WidevineCDM plugin has crashed" message and ceased to work .

No suggested fix works. Reinstalling does not help, toggling DRM application does not help. It was obviously the update (at least for users on 78.10.0esr with OS X 10.9.5) that did it. Is there some way to get this registered as a bug?

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

Hello,

This has been going on for few months and it doesn't seem to be going away (in fact, I see more complaints about similar issue around the net), so here it goes.

Up until Firefox 87 with Widevine 4.10.1582.2 I had no problems with Netflix. Then Firefox 88 with Widevine 4.10.2209.1 was released and every time I watch an episode of a show the screen freezes for several seconds while sound goes on. If you rewind and reach that point again, it doesn't happen again. However it's inredibly annoying when it happens at the climax of every episode.

I stopped updating Firefox beyond 87, but then Widevine 4.10.1582.2 stopped being supported and had to update or not being able to watch Netflix at all. While I can still watch movies, I had to start using Edge to watch tv shows (and I really don't want to do that).

I haven't noticed it happening on a movie, possibly because the last few minutes are credits which I don't watch. But there's a possibility it only happens on episodes. This is only my suspicion, but it happens right after the episode finishes buffering, so maybe it has something do with that or maybe some process with next episode is beginning while the current one is still being watched.

I'm not exactly sure it's something you can fix on your end since it seems to be involving Widevine, but would be great if something could be done.
