Very nice. A suggestion:

1. Make the window movable. I'd like to move it away from the browser screen preferably on my second monitor. And the menu shouldn't disappear when I click on a bookmark when it' not over the browser.

This review is for a previous version of the add-on (1.3.1-signed.1-signed). 

I'm sorry to disappoint you but right now I can't implement this functionality because Add-on SDK is kind off limited, and I can't make that panel moveable. When it will be supported I assure you that i will implement them right away. Anyway thanks a lot for your support and for suggestion.
