Feature description:

Currently tabs do not mute by default. Users need to use a secondary menu to selectively mute tabs. Additionally, the mute state of a tab is displayed in a small icon which is difficult to see.

I propose a new behavior that will give users more transparency about the mute/unmute. UX for this should be similar to the pop-up blocker. Users will be able to set a default behavior for mute state. They can then choose how to handle mute for each site as they can for pop-ups today. They should also be able to temporarily allow audio on a site.
