Nevermind, browser cache issues after an update from 6.0.2 to 6.1.2.
Sorry for the inconvenience.

No addons, and addblocker disabled.
I actualy find the problem, it was browser cache.
When testing in Chrome and all worked fine, that gived me a clue of a clean browser cached files, since i only use FF.
Deleted all cache on FF and now it works fine.
