Newsblur favicon count от Michael P. Geraci

I like to keep my Newsblur pinned in a tab, but then I don't know when I have unread stories... or how many. This plugin helps by overlaying the number of unread stories on the Newsblur favicon.

Note: for the add-on to work, you must turn on the "Show unread counts in the window title" option in your Newsblur preferences.
