So there's a couple of sources, like the (rather outdated) Mozilla wiki page detailing the sandbox support on Linux.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.

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.

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