one of the best , BUT.... Rated 3 out of 5 stars
One of the good reason to move to Firefox.
But it's way too large , icons are huge.
Should have ,at least as an option, a way to minimize the icons - somting like have done in some theme like littlefox , liquifox and other.
It's largeness make it impossible to use it with TabSideBar and AIOS.
