SimpleCookie Firefox

SimpleCookie

A minimalist yet efficient cookie manager for Firefox

Features & Capabilities

SimpleCookie is the easiest and fastest way to view, learn about, and delete cookies. It also serves as a configurable cleaner. Remember that cookies and related data are often very useful, so please use this add-on with caution, read the description carefully, and report any bugs or feature requests on GitHub.

  • Cookie fetching: SimpleCookie supports all cookie jars (containers) and partitioned cookies (3rd party, CHIPS) and displays a list of websites with the corresponding number of cookies.
  • Domain aggregation: SimpleCookie consolidates cookie subdomains under a main domain for clarity. It includes hundreds of exceptions for specific Second Level Domains (SLDs) used in various countries (e.g., .co.uk, .gouv.fr).
  • Organized list: Websites are sorted alphabetically for easy access. Sites storing cookies with an open tab are shown in green and can be displayed at the top. The active tab's domain is highlighted, along with sites in special containers or with partitioned cookies.
  • Detailed view: Right-clicking on a listed website opens a table with detailed information about its associated cookies. Right-clicking additional sites consolidates this table with more cookies.
  • Effortless cookie removal: A single click on a website deletes all cookies associated with that domain. Clicking on a specific cookie line in the detailed table removes only that individual cookie.
  • Safety first: A 'star/favorite' icon allows you to protect cookies from being deleted. A 'backwards' icon appears in the Dock to undo the very last cookie deletion you triggered. A confirmation prompt also appears for the Dock shortcuts. An export/import function (JSON format) allows you to back up your cookies. Many footnotes have been added for educational purposes (icons, table headers, settings, etc.).
  • Cookie editor: An option in the settings allows you to create a new cookie from scratch. An edit option is available from the detailed table.
  • Dock shortcuts: The 'broom' icon deletes all cookies from websites with closed tabs while retaining cookies from open tabs (highlighted in green) and your favorites. The 'sniper' icon deletes specific domains from your 'Most Wanted' list, except your favorites. The 'vacuum' icon deletes all cookies stored in Firefox except your favorites. The 'missile target' icon launches the myCleaner feature, allowing you to clear your selected browsing data. The 'gear' icon opens the settings.
  • Cookie counter: Display the number of cookies for the active tab over the icon.
  • Tab switcher: Hold Command (Mac) or Ctrl (PC) to enable the Tab Switcher feature so that a left click on one of the open tabs highlighted in green will switch to it.
  • Tracker database: SimpleCookie uses an internal tracking database derived from Ghostery (trackerdb) to identify organizations/websites known to track behavior (ghost icon). While this does not confirm the collection of data in requests and cookies from these sites, they are known for their impact on user privacy.
  • Theme options: Light and Dark themes work seamlessly with Firefox's theme settings. The add-on also uses a system font that should be appropriate for the OS it runs on (macOS, Windows, Linux).
  • Privacy policy: SimpleCookie does not collect any data, and there is no analytics or telemetry in the code. This is just an open-source hobby project designed at the begining just for myself, an indie dev (I'm not even a developer; I'm a researcher!) who is concerned about privacy. SimpleCookie uses the following permissions to work properly: all_urls (for domain aggregation), browsingData (to clean up the dust!), cookies (of course!), tabs (to identify the active and closed tabs), contextualIdentities (for the containers), and storage (to store the settings).

Is SimpleCookie Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

SimpleCookie requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details
  • Critical Grants access to browser tabs, which can be used to track user browsing habits and history, presenting a privacy concern.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

SimpleCookie is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
