Try to share screen on ubuntu, leads to console error in Firefox

Object { name: "gum.screensharing_user_canceled", message: "User canceled screen sharing prompt",

I didn't get a prompt to cancel, so not sure why its saying that?

It was the same for the person on Windows using Firefox as well. (both using stock browser settings)
