Works very good... Puntuado con 5 de 5 estrellas

...but you should not have browser's 'referer' disabled!
(which usually is enabled by default, but some people -like me- use the browser with the referer always disabled, for privacy reasons)

I wrote a review here some time ago, having no clue why this extension failed for me. So this new review is due to my decision to give it another try and to trace the origin that caused my former problems. I hope this helps other users who might have similar problems.
Now as it works for me, I like to thank you for the nice work.
