Click your user icon in the top right corner of the page, then go to "Settings". On the Site tab, turn Audio Theme off and check all of the "Don't show popup" options. Some things, like Bailey's announcements and quest completion, cannot be turned off. Notifications cannot be turned off either, but they're tucked away in the toolbar. They can be cleared with the "Dismiss All" option in the upper right corner of the notification drop-down.
