We use Slack at Evergreen to chat amongst our team—like pretty much everybody else in the world these days—and I like to use the web app versus installing a desktop app, because it works great and keeps things in one browser.
Among many of Slack’s settings are notification sounds you can choose from. I picked one that I liked: a simple but pleasant ding, and got back to work. When the first notification hit, it was bizarre. I could hear the ding, but it was in the midst of a cacophony coming through my headphones. There was a much different notification sound happening at the same time.
It turns out that web desktop notification support is built into the computer’s operating system. Not only was I getting Slack’s notification, I was also getting the notification set for Firefox at the same time.
Fixing the problem is easy, but there is a caveat.
- Open up System Preferences
- Click on Notifications in the top right corner.
- Choose Firefox.
- Uncheck “Play sound for notifications”
The caveat is that you’re disabling the sound for all notifications coming from your browser. That means other non-Slack notifications will also fall silent. I don’t mind, because Slack is the only web app I use that uses these alerts. If you use more than that, you may want to go the opposite route and turn off notification sounds in Slack instead.
