Annoying bug Puntuado con 4 de 5 estrellas

Would be a very useful extension, but does not work correctly.
When opening a bookmark, the target has to be a new tab!
Usually, starting a new browser session, there is an empty tab already.
On the other hand, the BookP-addEventListener function triggers "TabOpen" events only, so IMO the extension fails.
