DRM Widevine media issue

Hi, I can't read some DRM protected media anymore (Prime video, Spotify) in Firefox in Windows10.

The error I get say that firefox doesn't have Widevine installed (but it does).

I can read the content with other browsers (Brave) so the problem is not Windows Media Foundation i guess?

What I already tried:

-untoggling/toggling Widevine in plugins

-reinstalling firefox and using a new profile

-using Firefox Nightly

-removing the drm folder from the profile and relaunching firefox


Output of the console:

You can toggle DRM off/on to see if that makes Firefox (re)load DRM components.

You can check the connection settings and check for possible issues with a Proxy or VPN service.

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

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

Hi cor-el, thanks for your answer!

-I already tried toggling DRM without any effect.

-Right now "No Proxy" is selected in the networks settings, I also tried "Auto-detect proxy settings for this network" but it doesn't change anything
