When you open a game's page on Steam, IGDB or GOG, a small badge shows its status in your GameTome library (playing, completed, backlog, wishlist…). One click changes it, without leaving the page.
How it works: sign in on gametome.app, go to Settings › Extension, create a personal code and paste it in the extension popup. The code stays in your browser and can be revoked at any time from the same settings page.
The extension only runs on game pages of Steam, IGDB and GOG, and only talks to gametome.app. It does not read other pages or your browsing history.

You need a free GameTome account (https://gametome.app). The card shows up on game pages on Steam, GOG and IGDB. If it doesn't, open Firefox's Extensions menu and check that GameTome is allowed on those sites. Questions and bug reports: https://gametome.app/support
