After some more digging, I have discovered that WebRTC is disabled by default in armhf builds of Firefox. I was able to enable it via installing the WebRTC Control add-on in Firefox.
After enabling it, the complaint of the unsupported web browser goes away, but the camera and microphone do not work. I suspect that may have to do with device mappings inside the container.
