Perhaps similar to * https://support.mozilla.org/en-US/questions/1309405 * https://support.mozilla.org/en-US/questions/1295127 Computer: Dell Inspiron OS: Ubuntu 20-04 FF: 88.0.1 I have two cameras attached to my system: one is the integrated camera and another is an external webcam. Firefox is able to recognize the webcam's mic but not it's camera. Pulseaudio has the webcam mic as the preferred audio source and firefox is picking that up, but I know of no facility to choose from all attached cameras either within or without firefox. How can I tell firefox to use the webcam camera?
