Puntuado con 4 de 5 estrellas
I'm using the latest version on Firefox 17 and I see no adds. Honestly. Perhaps because I have several anti-adds and privacy add-ons installed or whatever, but I haven't seen a single add so far.
This add-on doesn't get its fifth star because it sometimes gives an error that it can't save the image because it is too large. It is a bug that has never been fixed and has been carried over from version to version.
