I also just checked the sandboxing status directly in Firefox.
And I’m kinda of cheating, I knew they used it since I’ve got an unsupported configuration with HW video decoding. It’s caused by their sandbox blocking certain things, and it’s a known issue. Nvidia drivers don’t support VA-API, Firefox only supports VA-API. There’s an adapter library available, but it doesn’t work in Firefox unless you disable the sandbox.
So, there is still the problem with the sandbox and the only way you have hw acceleration is to disable the sandbox, I bet it is elfarto VA API adapter library. And what about FF Android?
So there’s a couple of sources, like the (rather outdated) Mozilla wiki page detailing the sandbox support on Linux.
And I know it’s specifically the Chromium sandbox, since they vendor their copy of it.

Edit: Oh yeah, Firefox is also affected by the same issue Chrome is, where Flatpak interferes in the sandbox.
Very cool
