What is Cookie AutoDelete?

Cookie AutoDelete is a user-friendly Firefox add-on inspired by Self Destructing Cookies. It imparts significant control over cookies by automatically deleting unused cookies when a tab closes. This add-on supports whitelist/greylist for domains, manual mode cleaning and container tabs while also showcasing the number of cookies for a site. It protects user privacy and optimizes browser performance. Noteworthy, it requires enabling cookies in the browser and facilitates disabling cleanup notifications via the settings.

As of Firefox 86, strict mode is not supported at this time due to missing APIs to handle the Total Cookie Protection. Also as of Firefox 103, standard mode has also enabled Total Cookie Protection. Use 'strict' mode if using pre-86, use standard mode for versions 86-102, or from version 103+ use the custom configuration and set cookie to 'cross site tracking cookies' option (not the cross-site cookies).

Before opening a GitHub Issue, please check the troubleshooting FAQ first. Note that support may not be available for variants of Mozilla Firefox and Google Chrome.

Permission Request Explanations

  • Access your data for all websites: CAD requests this to delete cookies and other site data for all sites
  • Clear recent browsing history, cookies and related data: Ability to delete site data by domains.
  • Display notifications to you: Self explanatory.
  • Read and modify privacy settings: This setting has been removed since 3.4.0 and is kept here for historical reasons. Automatic detection of First Party Isolation support. Although the Privacy permission gives CAD "read and modify" permissions, NO MODIFICATIONS are done to your privacy settings, CAD only reads the setting of First Party Isolation. The privacy permission unfortunately cannot be given granular control, so this will stay for now.
  • Access browser tabs: CAD uses this permission to display the site hostname in the popup for easy whitelisting/greylisting, displaying the amount of cookies for that site, and which rules apply to that site.

Take the permission wording with a grain of salt.
