When I have unread slack messages, the Slack icon on the browser tab is a bright white (with a red dot when I get a mention):

When I have no unread messages, it is grey:

Is there anyway to disable this "badging" so the tab does not change at all, regardless of whether or not I have unread messages? I have Slack notifications disabled in Chrome, but this only affects the little notification pop-ups. I know that I can mute channels in Slack to not get any form of notification, but I just want to control of the tab behaves, because I would still like to see an indication in the Slack sidebar of which channels include unread messages when I visit the Slack tab itself.

You aren't alone in this request, however it isn't possible at this time. The Slack Twitter account responded to this question only last month:

Ah, it is unfortunately not possible to disable favicon auto update or mute direct messages. Sorry to be the bearer of bad news. 🐻 - @SlackHQ


  • Thanks for the info! That's unfortunate. I love it when software companies try to be cute when delivering bad news...

You can use Tab Modifier to change the Icon to a permanent Icon that won't change when receiving messages. Just add the rule for your slack and change the icon, then refresh the slack page. Maybe a bit overkill of a solution, but it works.
