Outstanding! Rated 5 out of 5 stars

EDIT [1/31/2013]
DuckDuckGo just released version 0.2.15 which fixes the toolbar button reset issue. As promised, I now rate this add-on 5 stars.

Again, thank you for providing us with DuckDuckGo.

Long time DDG user, new DDG for Firefox addons user.Normally I manually integrate DDG to my Firefox installation thus adding most of the features the DDG for Firefox addons adds to Firefox but I found the "highlight" a word for a definition and the "in the awesome/url bar instant definitions" enough of a reason to make me give this addon a try. To my disappointment there is a bug preventing me and several other users from removing the DDG for Firefox button for after restarting Firefox the button resets itself back to the navigation bar.

The DuckDuckGo addon developer asked for proof. I made a video http://youtu.be/oNW8VSIQXpEWhen the bug is fixed the addon will deserve a full 5 stars

This review is for a previous version of the add-on (0.2.13.1-signed). 

Thanks for the video!

Thanks for the details---we're still investigating but that helped a lot :) If you're interested in a DDG shirt, feel free to let us know through the form at the bottom of this page: https://duckduckgo.com/feedback
