FicTracker

Add any fic to your FicTracker library with one click. Set your reading status, advance chapters with +/- controls, and see your current progress — all from a compact floating panel that lives on every AO3 work page. The extension auto-detects which chapter you're on and silently syncs your progress as you read. When you finish the last chapter, it marks the fic complete automatically. Three panel modes let you choose how much space it takes up: full (status, chapters, and controls visible), mini (a slim pill with just your status and chapter count), or hidden (a small floating button you can expand when needed). Your preference sticks across pages. Works with FicTracker (https://fictracker.vercel.app) — a free reading tracker for AO3 readers. Sign up for a FicTracker account to get started, then install the extension for seamless chapter tracking while you read.
