Amazon Prime Video won't play

The 125.0.2 update broke Amazon Prime Video. Firefox refuses to play ANY video, causes website to return a "That shouldn't have happened" error page. Prime Video plays just fine on Safari 16.6.1, macOS 11.7.10. Amazon says just to use Safari, but I want Firefox to work right.

Here's a direct link to go back to 125.0.1: https://ftp.mozilla.org/pub/firefox/releases/125.0.1/mac/en-US/Firefox%20125.0.1.dmg

I'm curious to see if that really gets Amazon Prime video working again. Let us know if it does.

Does it still happen in Troubleshoot Mode?
