Cookie Workshop for Firefox by jakcbv

cookie workshop for firefox is a firefox-focused cookie manager based on the open-source editthiscookie (v3) project. it lets you view, add, edit, delete, search, import, and export cookies, manage cookie protection and blocking rules, and inspect cookies from devtools.

the firefox edition adds a native sidebar that understands firefox cookie stores and containers. you can switch between cookie stores, focus on the active website, filter cookies, and copy store-specific cookie data as json.

no account is required. the extension does not include analytics or telemetry, and cookie data stays inside firefox unless you explicitly copy or export it.
