AO3 Filter by Harshal-R-Maru

AO3 Filter gives you complete control over your Archive of Our Own browsing experience. Hide works by author, tag, language, individual fic, or anonymous status, all with a few clicks. Use convenient in-page buttons to block content instantly or manage everything from the extension popup. Your filters are stored locally, automatically applied on every AO3 visit, and work for both logged-in users and guests. You can also import/export your block list and optionally generate CSS for AO3 Site Skins.
