Five Stars till update 1.1. - Since that add-on doesn't work anymore :(

To reply on your comment:
My OS is Windows 11 Pro 25H2
Updated the add-on to version 1.1.1
Cookie Remover Popup says "All cookies & site storage purged for: cnn.com" but all 14 cookies that where present before are still there.

After the 1.1.2 update, it deletes cookies—though not all of them.
