Type: -- → defect

I guess I may as well fix this.

Assignee: nobody → emilio
Component: CSS Parsing and Computation → Audio/Video

Preferences::GetBool is not thread-safe, StaticPrefs are.
Also StaticPrefs are nicer anyway.

There's a lot of Preferences:: usage in dom/media which looks suspicious, though
I don't know if all that runs on the main thread.

Aaron, Jean-Yves that's way over my knowledge of the media code, but looks like this fix uncovered yet another thread-safety issue... Is there any chance any of you could take a look and finish this?

Alternatively I can land it as still-crashing on windows or something I guess... That's probably slightly better.

I'll file a dependent bug. I've been thinking about fixing EnsureMTA so that we can eliminate that assertion anyway.
