Smart Cookie Editor od EvlarSoft LLC

Smart Cookie Editor shows every cookie the page in front of you is using, and lets you change any of them without guessing what the browser will accept.

SEE EVERYTHING THE PAGE USES

Cookies set for the site itself, for its parent domain, and the partitioned cookies that embedded frames keep. Switch to All sites to browse every cookie in the browser, grouped by domain.

EDIT WITH THE RULES CHECKED

Change the name, value, domain, path, expiry, SameSite, Secure and HttpOnly. The browser rejects a bad cookie with the same vague error every time; Smart Cookie Editor checks its rules before saving, says which one a change breaks, and fixes it in one click. Values decode as you type: URL-encoded text, JSON, Base64 and JWTs.

NOTHING IS FINAL

Every delete can be undone. Export what you see as JSON or cookies.txt.

PRO

Profiles save a site's cookies so you can switch accounts without signing out. Import from JSON, EditThisCookie, Cookie-Editor or cookies.txt. Clear tracking cookies on a schedule, with a list of sites that are never touched. Insights show every cookie in the browser at a glance.

Everything stays in your browser. The only thing sent anywhere is the licence check with Gumroad.
