Another one I haven't seen mentioned is joyreactor/safereactor. It's especially good for finding Library of Ruina works and very early art of Lobotomy Corporation (oldest goes back to March 2017, just ~3 months after it went into early access.)
The main caveat is that it tries to slap a watermark under the image if you try to save it while scrolling. You need to either open the image in a new tab before saving, manually crop it, or use some kind of extension like save as PNG to get around it.
