Doesn't work on Firefox 78.0.2 (_DRM_FAILED_LICENSEREQUEST), and on the latest Firefox release description key has changed. I suppose that key are hidden in file $PROFILE/gmp-widevinecdm/4.10.2209.1/libwidevinecdm.so, but that's a binary file, intentionally obscured in addition. There must be any way to extract that key and use it to break drm.
