Rated 4 out of 5 stars

It works. I'd like to be able to see the counter in the title bar too. And I can't seem to get font size/family/weight to do anything. No matter, leaving the color blank defaults to the theme font color and that looks nice, after I moved it from the tab bar to the URL bar.

This review is for a previous version of the add-on (1.9.6.1-signed).
