hello stefan,

unfortunately, that pluggin widevine has created a firestorm of complaints.

below is a link to a discussion on this with some resolutions provided.

but in my opinion, its best to revert back to a functional version of the FF, that the specific version of WideVine worked on

afterwards, disable the FF updating to keep that version locked with the o.s. version you have.

Doesn't help with Mac OS 10.9.5 Widevine only supports 10.11 or later. Looks like back to Safari for me :(

thanks for the additional info!

i brought up the issue of widevine on yesterday with other Mozillians. There is a fix in the works.

btw: does safari work for those sites where widevine does not?

any update on this? it is really horrible what they have done to old OS users. thanks!

There is no way to get an older Widevine version working as only Widevine 4.10.2209.1 can retrieve a valid license from the license server to play DRM protected files and this Widevine version requires macOS 10.11 as a minimum. Google has revoked all older Widevine versions.
