I have the latest version of Firefox 78.15.0esr (64-bit) on my Macbook Pro. Netflix says, "Looks like your browser is no longer supported. Please install the latest version or install another browser. Error Code F7121-3078" (see image 1).

Netflix streaming works fine on Opera, but I can't get it working on Firefox, even though it was working fine on Firefox a couple of days ago (Sept 15, 2022). Any help you can offer would be appreciated very much. I have two plug ins: Facebook Container and EFF Privacy Badger. There is no update available to update Firefox. It appears that when the new version of Widevine updated yesterday (see image 2), the browser stopped working for streaming on Netflix. Widevine version 4.10.2209.1 (updated Sept 16, 2022).

If you had macOS 10.12 (ten.twelve)or later you would be able to use more current versions of Firefox.
