do they never go away or do you have to click them twice?

Click the notifications icon, click it again to close the menu. Notifications should be marked as read.

And fair warning: blocking cookies and/or JS will probably break things unless you make exceptions in your extension's settings. JS is required, and at least the _qpixel_session cookie must be allowed for things to work properly; we may support no-JS better in future, but right now we don't have the dev time available.

@ArtOfCode Clicking the menu again worked. However, it seems a little counterintuitive for me as I click on a single notification to get to the newest content and don't browse all notifications at once. So if I click on one notification, I only want this one to be read and the others to be still available for me (for a later time). So no bug in the end, more like a feature request :-) Thanks for helping me!

Yup, that is a bug, notifications are supposed to go away once you've clicked them, one by one instead of all at once. But... notifications are in need of an overhaul anyway, so when we get to that we'll fix the dismissal bugs too.

@ArtOfCode Reconfirming bug on firefox; clicking the notification to go to the specific site does not clear that notification, it must be explicitly marked as read, and the small blue (1) doesn't disappear until the page is reloaded, no matter if the notification is marked as read or not.
