MFC Lookup by Adamovix

Open a product page on a supported shop and a small panel docks to the bottom-right corner: it finds the matching MFC entry by barcode, tells you if the figure is already on one of your lists, and lets you add it to your Wishlist, Ordered or Owned list without leaving the shop.

Features
- Automatic MFC matching — figure's JAN/EAN barcode is looked up on MyFigureCollection and verified against the item page
- One-click adding — add the figure to your Wishlist, Ordered or Owned list, with a wishability rating (wishlist) or score (owned).
- Knows what you own — if the item is already on one of your lists, the panel shows a badge (with your stars/score) and pre-fills the controls, so you can update rating/score instead
- Stays out of the way — the panel collapses to a slim orange MFC tab on the screen edge; a setting can keep it collapsed by default.
- Privacy — it uses your existing MFC browser login. No credentials are ever seen, stored or sent anywhere else.

Important
A background MFC tab is required — MFC sits behind Cloudflare, which blocks direct extension requests; all MFC calls run through a real MFC tab (pinned by default, hideable on Firefox).
