Only allows sound from whitelisted sites.
Version 1.0: Please send comments, bug reports to firstname.lastname@example.org. See new features below description.
Sick and tired of sites that make noise without your permission? Silent Site Sound Blocker maintains a white list of sites that only you allow to play audio. If a site is not on your list and tries to play sound, you'll get a prompt which gives you the option of whitelisting it forever, allowing the sound once or rejecting it.
You can also configure Silent Site to work on a blacklist only model which bans only those sites you designate. Right click the toolbar icon to change modes or instantly blacklist / white list a site. Select "Options" to edit your white and black lists.
Note: You must have Tab audio muting enabled in the Chrome://flags menu. However, for most users this is enabled by default.
Changes for version 1.0:
1. Option to "block all background tabs" in options menu.
2. Option to "never block pinned sites" in options menu.
