GobStopper par Aligorith

Pauses all HTML 5 videos/audio with just a single click on the toolbar icon or by pressing F4.

This is useful when working in an office environment where you may be frequently interrupted while listening to music on Youtube or other video/music streaming sites, and it is not always convenient to be riffing through your open tabs closing the sound-making tab in front of co-workers, bosses, clients, etc.
