Which video? Did you update to 95.0.2? Did you try Firefox in Safe Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#w_how-to-start-firefox-in-4troubleshoot-modesf5safe-modesf

Hi, this is getting ridiculous. I have gone through the process of upgrading/updating Firefox so that i can watch videos on Amazon. I finally get to the end of the process and then I'm told that Widevine Content Decryption Module provided by Google Inc. will be installed shortly. This was two days ago and I'm still waiting with no progress. Someone please tell me what's going on, PLEASE! This is making me real angry, i've been really inconvenienced by this. Thanks Alan

First, reboot the computer. This will clear any problems.

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.

• Settings -> General: Play DRM

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