This is not related to bug 1524665, but to the web page that implements the camera stuff, which is orthogonal to the Firefox button.

The behaviour from the browser is as expected. I guess the web page could provide a more detailed error when getUserMedia rejects with NotAllowedError, and show an error along the lines of "You need to allow us to use the camera" .

This is expected behavior of Firefox. If you look in the URL bar you'll see the temporary permission modification. There is also a clearer error on the page now the second time you go back. Closing this as wontfix as it's intended. Thanks.
