Really great add-on, makes navigating on Pixiv really light and quick. Like the other review, it would be great to have a button to load the page without the changes, giving access the similar pictures thing, then it would be a perfect add-on.

Really cool idea, but would be really nice if you keep "similar images" thing, because it's main tool for discovering a new art. At least make it optional please. Hmm, actually if you consider doing it then it would be rational to make "display all images automatically" optional too, since it will be pain in the ass to scroll all the way down if you just wanna check similar images.
