Only allows sound from whitelisted sites.
Version 1.1: 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 1.1:
* To fix a bug with Google sites such as Gmail, the whitelist / blacklist lists whole domains (ex: google.com), and not subdomains (ex: gmail.google.com) any more. This solves a problem where certain web tools loaded content from multiple subdomains and were not properly listed. For example, gmail.google.com did not stay whitelisted because the site loads from notifications.google.com in the background.
* Bug fix for pinned sites: If you configure the extension to whitelist all pinned tabs, the pinned tabs will now remain whitelisted even as you move from one page to another. However, due to how Chrome captures events, if you have this option enabled, a tab will not unmute as soon as you right click on it and select "pin." It will instead unmute on the next site load or active tab change.
