Want your browser to display a notification when people reply to you, message you, mention you, etc. in a post?
Step 1: Click on your avatar on the top right corner. Then click the 
icon to go to your preference.
Step 2: Click Notifications from the list on the left side of the screen.
Step 3: Choose either Desktop Notification or Push notification.
Desktop notification notifies you when you have the site open in your browser. Push notification notifies you when your browser is running, whether you have the site open or not.
Result: Viola! A little notification box will pop up briefly from now on when you have a notification.
