A great addon that should've been built into Firefox Rated 5 out of 5 stars
This add-on is a dream come true for those Firefox users that have been seeking for a tool that will transfer all their add-on bar items to inside the url bar with a clean and minimalistic look.
The user can add/remove/reorder add-on bar items as they wish, and after you are done you will see them neatly lineup in the url bar.
Lastly, I want to mention that this add-on has been very stable for me. The only scenario this add-on "might" malfunction is if you have other active extensions/themes that alter your url or add-on bar.
I want to say thanks again to the developer zibinlin for making this great add-on!
