Is it possible to create a whitelist for when I deleting cookies and history at once? Recently, the number of sites that log in and authenticate by reading the QR code with a smartphone has increased, so I do not want to whitelist and delete cookie of such sites. It's very annoying to re-authenticate with your smartphone every time. But other than that, I want to delete everything every time I log off.

Detail like websites remembering you and log you in automatically is stored in a cookie.

You can use these steps to make a website recognize and remember you.

  • create a cookie allow exception with the proper protocol (https:// or http://) to make a website remember you

You can check that you aren't clearing important cookies.

  • using "Delete cookies and site data when Firefox is closed" keeps cookies with an allow exception
  • using "Clear history when Firefox closes" to clear cookies clears all cookies including cookies with an allow exception you may want to keep
  • clearing "Site Preferences" clears exceptions for cookies, images, pop-up windows, and software installation and exceptions for passwords and other website specific data
  • Options/Preferences -> Privacy & Security
    Cookies and Site Data: "Manage Exceptions/Permissions"
