5 stars again from me :)

Old comment:
Hello,
this is really good add-on, but version 4.9.11 doesn't work for me. I click on filename to download and nothing happens. I have windows xp sp3, newest firefox, only firebug and istockzoom plugins installed, so my FF is kinda clean.Version 4.9.10 works fine, but it keeps update to the newest version.

Please fix the bug with 4.9.11, and I come back here and give 5 stars, because before broken version it was really great add-on!

Esta valoración es de una versión anterior del complemento (4.9.11). 

Thanks for the review update.
