Auto-delete Firefox cookies for just one website

+6
−0

Firefox "Settings" offers a checkbox for "delete cookies and site data when Firefox is logged off."

Is there a way to configure Firefox to have the cookies for one specific site deleted when Firefox is logged off while preserving cookies for other sites?

If so, how can this be done?

Screenshot from Firefox Settings section on Cookies and Site Data. There is a checkbox for "Delete cookies and site data when Firefox is logged off", as well as three buttons: "Clear Data...", "Manage Data...", and "Manage Exceptions..."

A quick search shows some extensions that might address your problem. I give my quick read on how they work, but haven't tried them. They are worth giving a shot or searching for others.

Cookiebro https://addons.mozilla.org/en-US/firefox/addon/cookiebro/ Has a cookie blacklist, though make always delete cookies.

Cookie AutoDelete https://addons.mozilla.org/en-US/firefox/addon/cookie-autodelete/ Deletes cookies on tab close, but appears to require a whitelist to not delete cookies, with no option to use a black list instead.

Thanks for doing this legwork.

Unfortunately, although Cookiebro looks like it originally had the functionality I'm looking for, the most recent reviews indicate that the addon has not had any updates since 2021, and that it stopped working in Firefox sometime in the past year: https://addons.mozilla.org/en-US/firefox/addon/cookiebro/reviews/
