CookieTin Extension Manages Partitioned Cookies Across Firefox, Chrome and Edge
Developer Perruer2 has released CookieTin, an open-source browser extension that fully supports partitioned cookies under Firefox Total Cookie Protection and Chrome CHIPS. The tool addresses limitations in older managers like Cookie Quick Manager by correctly retrieving and deleting cookies stored with partitionKey values. It works across Firefox, Chrome and Edge using a single Manifest V3 codebase written in TypeScript and Preact. Key features include accurate cookies.txt export compatible with curl and yt-dlp, protected cookies that survive explicit deletion, and pre-save validation of browser rules for __Host- prefixes and SameSite attributes. E2E tests using Puppeteer verify handling of HttpOnly, partitioned and container cookies in all three browsers.
