Cookie & Storage Toolkit

Manage cookies, localStorage, and sessionStorage with import, export, editing, migration, and encrypted cookie files.

Cookie & Storage Toolkit gives you a compact browser data workspace inside the side panel or sidebar, so you can manage cookies, localStorage, and sessionStorage for the current website without jumping between settings pages or developer tools. What you can do: - View cookies for the active tab, including domain, path, value, and security flags. - View localStorage and sessionStorage for the active tab origin. - Filter cookies by domain and sort by cookie name or value. - Filter storage items by localStorage or sessionStorage and sort by key or value. - Select specific cookies before exporting or copying data. - Select specific storage items before exporting or copying data. - Add, edit, and delete cookies or storage items directly from the side panel. - Delete multiple selected cookies or storage items with a confirmation popup. - Copy cookie names, storage keys, and values quickly from each row. - Export selected cookies as JSON, Netscape Cookie File, browser-console JavaScript, or encrypted `.cmp` file. - Import cookies from JSON, Netscape Cookie File text, pasted data, or encrypted `.cmp` files. - Export selected storage items as JSON or browser-console JavaScript. - Import storage items from JSON files or pasted JSON data. - Export and import migration `.mcmp` files that include both cookies and storage items for the current site. - Use password-based encryption for sensitive cookie export files. - Work with a compact dark dashboard interface designed for repeated developer and QA workflows. Why install it? Cookie & Storage Toolkit is useful for debugging login states, testing user sessions, moving cookies and web storage between environments, checking cookie flags, and keeping cookie export files safer with local password-based encryption. Privacy note: Cookie and storage data are handled inside the extension and browser APIs. Encrypted exports are protected with the password you enter, and the extension does not need an external server to manage your browser data.
