When I visit some online camera call website with webRTC by iceweasel on Raspberry PI 2, it will ask me share camera and microphone.
No meter I select 'Share Selected Devices' or 'Always Share', they work fine.
However if I select 'Always Share', next time I visit this website, it will access camera and/or microphone fails. I must clear 'Site Preferences' and refresh.
How can I force share my camera and microphone without showing the confirming window.
