Peacock no longer works. I can sign in, but the main menu appears for a split second, then the screen goes black.
I used to be able to log into Peacock without issues. Either Firefox changed something or Peacock did. But it no longer works correctly. I can sign in, but the main menu appears for a split second, then the screen goes black.

Might be just some stale session data accumulated over time, try e.g. a Private Window to get a clean start to see if it's still the same, and then can move forwards with cleaning caches, cookies and site data selectively.
I'd start with running Troubleshooting Mode first: Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and if it's still broken there's steps how to report webcompat details with How do I report a broken site in Firefox desktop?
