Fantastic extension, my only complaint is that I can't get it to appear on the toolbar, so when I have to tweak it with a new blocking criteria I have to go into the hamburger menu > add-ons > options. Which is annoying. Toolbar button, please!
If you are on an AO3 page there should always be a "AO3 Enhancements" button present on the AO3 page itself. It should be right after "About" in AO3's main navigation bar. Hope that helps :)
