Widevine Content Decryption Module provided by Google Inc

I use Firefox as my primary browser, and I tweaked the settings to make it more privacy respecting. I just found in Settings, under Plugins, something enabled by default called “Widevine Content Decryption Module provided by Google Inc.”

What kind of information can Google collect from me if I use this?

Official Firefox for Android already contains proprietary Google libraries, consider instead using the fully free Fennec F-Droid or my Mull.

And Widevine on Android is backed by both a userspace and TrustZone implementation already running on your device.

The Replicant project removes Widevine and PlayReady.
My DivestOS removes Widevine, PlayReady, and ClearKey and has done so for the past 5+ years.

I use Firefox on my desktop. I am not so paranoid about anything Google, I just don’t want them tracking me, so I wanted to know what information about me Widevine gives them.
