Rated 5 out of 5 stars

I've been using this add-on for probably more than an year already, and I have to say that it's really amazing. Every time I install Firefox, this is one of the first add-ons I get.
It would only be great if it used Firefox's high quality downscaling, when the pictures need to be downscaled to fit the window, to reduce the aliasing.

This review is for a previous version of the add-on (2.6.1-signed).
