Rated 4 out of 5 stars
It works initially, for a little while. But after that (either closing and reopening the browser or simply having it open for a while) it stops updating the status text (link hover and network text) leaving one with a blank add-on bar again and no text. It's really buggy and can't be relied upon as a replacement for the status bar.
EDIT: this seems to have been a bug that is now fixed. THANK YOU!
