title: How to add a dropdown menu to a firefox addon sdk powered addon toolbar button?
body: <p>I use the <a href="https://github.com/erikvold/toolbarbutton-jplib/" rel="nofollow">https://github.com/erikvold/toolbarbutton-jplib/</a> package to add a toolbar button from an addon-sdk addon to the firefox navigation bar. Is it possible to add a drop down menu to this button (as I understand there are no easy ways)?</p>
