Is this possible using an extension for chrome or using a 3rd party app?
It looks like the chrome toolbox extension won't mute for mac yet. Not sure why and would love an explanation/rebuttal by someone who can solve this problem.
This chrome toolbox extension allows you to mute tabs.
Do the following:
Install the extension. It will show a small icon (with an m) in the top right of your browser. Click that, and you are given an option to mute all tabs. Alt+w is the shortcut.
