Rated 5 out of 5 stars
Useful add-on for quick access to add-ons dialog box. Just one suggestion: a drop down menu with an item "addons.mozilla.org" would be nice which would navigate you to AMO.
Or a right click for the same purpose. IMHO every bit of space on a toolbar/statusbar has to concentrate as much functionality as possible - without being obscurely overburden. Thank you for this one István.
