very good implementation Rated 5 out of 5 stars

the icon seems stable to me, currently in the addon bar, bottom right [it disappeared but all i did was go to addons and disable it, then enable again, and the button re-appeared]
- i would like to see a navigation button and close button in the top right of the frame, but the usage of the addon bar button works fine

Nice idea but the toolbar button for using it keeps disappearing without a trace, meaning that you can't find it in the customize window at all. Sometimes it might come back for a short while, only to be gone again soon afterwards (FF 26). Some other restartless add-ons display the same behaviour, but at least one can find the button and reinstate it in the toolbar.

neat add-on, excellent idea.

it should be better if it opens the panel on a new tab, but it has been very good now, five from me.
