it hides the banner picture

A good extension, but there are disadvantages.
- does not switch between images using the keys
- you can't cancel adding to favorites
- does not show which images have already been added to favorites

It's a good addon, just wish it supported Firefox 48+ or atleast 55+ like other WebExtensions addons

would be perfect if it showed the most recent arts made by the artist relative to the one you're on, e.g the one shown on the right side of regular pixiv.

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.
