Cookie Manager

A modern cookie manager userscript with a clean floating UI. Works on Tampermonkey, Violentmonkey, Greasemonkey, Userscripts (Safari), Via Browser and any other userscript engine.

Features

  • Dual engine — uses the modern cookieStore API on Chromium, automatically falls back to document.cookie on Firefox/Safari/legacy
  • Full CRUD — add / edit / delete / batch-add with smart paste parsing
  • Multi-select — filter-aware select-all, bulk copy, bulk delete with one-click undo
  • Multiple copy formats — Cookie Header, cURL --cookie, JSON (DevTools / EditThisCookie compatible), KV
  • Import / Export JSON — back up your login state, share between devices
  • Detail view — tap a cookie to see Domain / Path / Expires / Secure / HttpOnly / SameSite / Size, with size warning at >4 KB
  • Undo delete — every delete shows a 5-second Undo toast
  • Bilingual UI — instant 中/EN switch, persists across sessions, auto-detects browser language
  • Search — by key or value
  • Draggable floating button — position is remembered

How to use

A small blue C button appears at the bottom-right of every page. Tap to open the manager. Drag to move it. The button position is saved.

  • Multi-select mode → bulk operations + filter-aware select all
  • Copy As... → choose the format you need (header for HTTP debugging, cURL for terminal, JSON for backup)
  • More ▾ → Export / Import JSON
  • Tap any cookie to expand its full details
  • Edit lets you rename the key, change value/domain/path/expiry — all editable
  • Switch language with the 中/EN pill in the header

Privacy

This script makes zero network requests. All data stays in your browser. No telemetry, no analytics, no remote calls.
