It does mute sites effectively but ignores the whitelist. I have tried adding both domain and url from the menu and also adding a regex manually but new tabs are always muted.

Are there suggestions for whilelist? Like a big list of sites that are commonly used? I am worried about needing to use support chats or something and not hearing chimes when they reply; and also streaming sites. Is there a kind of catch all that I can put in? like *.com/support or support.*.com ? Thanks

A simple and easy extension. Sadly it doesn't work most of the time. I whitelisted Netflix and YouTube several times (they appear multiple times in the filter list) and yet it randomly just mutes tabs. Switching to another extension now, there are way better ones out there.

Love this app. The only thing it's missing (unless there's an option I'm not seeing) would be the option to unmute a muted tab when you go back to it.

Nice job. It keeps free of tension from unexpected volume. Thank you very much

Seems to work just as it says. I've had it on my browser for over a month with no problems

Whitelist doesn't work in private mode.
