Nice addon Puntuado con 5 de 5 estrellas
Still works in the latest nightly changes except it's only good for the first tab, any additional tabs and it's broke. Otherwise excellent addon for the latest release with a lot of useful tweaks.
Update: the new version works good with the latest nightlies.
Firefox 25 (latest Nightly) introduces an almost new find bar, I'm currently working on making FBT compatible with it.
Edit: v1.3 should be fully compatible with Firefox 25's new find bar.
