Need to click on "New messages" twice to get the notification to disappear

When I click on
“New messages”, I get to see my new messages, but then I need to click on “New messages” again to get the notification to disappear.
Could this be fixed?
May be a FF related bug?

PS: I’ve seen the feature list on xls for developers, but that seems to be from 4 years ago - am I still supposed to post anything here to improve things, or not?


seems to be fixed now, quick work!

hm, no, it’s back (or rather, still there)
