Twilio developer evangelist here.
You have an issue with system resources here. One app can only get access to the camera at a time, so if it's being used by Chrome, then Firefox can't access it.
I recommend just testing in one browser, possibly using private mode so you can log in as a different user.
Make sure you handle the error case when you can't get access to the camera too.
