Rated 4 out of 5 stars

Very useful addon. A few glitches though:

- No matter what I choose in the addon options, I cannot remove the extra menu (intention is to only add a drop-down to the panorama button).

Of course, if I could disable it, I wouldn't care for the rest of the glitches (and I wouldn't have noticed them in the first place either), but here it goes...

- Selecting the option to *only* show group count shows an empty bracket next to the button name. Like so: "Tab Groups ()"

- Selecting to show *only* the tabs count shows an unnecessary forthslash in the next to the count. Like so: "Tab Groups (15/)". This might be required for when showing both tab count and group count, but not when there's only one of them shown.

- When starting up firefox the menu count on the new menu shows empty until I click on the panorama button drop-down. Shouldn't it be populated with the count(s)?

This review is for a previous version of the add-on (0.9.1.1-signed).
