Rated 4 out of 5 stars

Really a goooooood theme, nicely integrated in elementary os !
But 1 bad point, and very important : with de developper toolbar, the dots around the targeted elements are not visible... and it is very important for me, so I can't us it... :/ Is it possible to have this fixed ?
Thanks a lot :)

This review is for a previous version of the add-on (2.5). 

Zee and I are aware of this bug. When either of us get the time, we'll try and make a fix. It is one of last bugs for https://github.com/zeeeeee/firefox-elementary/issues/4. If you feel like poking around yourself, it would be very helpful! Diff'ing the original Firefox theme to our own is how we usually finding fixes.
edit: Oh, and I'm glad you like it. :) zee is amazing!
edit two: I fixed this particular bug. I don't think it's worth pushing for a new version here on mozilla.org so if you'd like to use it please follow instructions @ github.com/zeeeeee/firefox-elementary
