While trying to load: https://edition.cnn.com/
I got the tab to freeze, which then prevents devtools from loading (we have an issue where devtools can't be opened as soon as one content process hangs).
A first "nightly" profile: https://share.firefox.dev/4dfrA4N
And a few minutes later, a "media" profile: https://share.firefox.dev/3B7QPsE
Except this tab (and devtools), firefox was functional.
This was on Ubuntu 24.04.1 LTS, local build of today's mozilla-central (a51b9d3e7251d81217a4d7b3622a1658e9a23dfc).

mccr8 said: "Looks like mediasupervisor #1 thread is trying to sync dispatch to the main thread to get some service so maybe that's the problem?", this indeed like a textbook deadlock.
