I’m gonna copy-paste my comment here. Please, don’t install such extensions.

Cookie extensions

❗️Sanitizing in-session is a false sense of privacy. They do nothing for IP tracking. Even Tor Browser does not sanitize in-session e.g. when you request a new circuit. A new ID requires both full sanitizing and a new IP. The same applies to Firefox

❗️Cookie extensions can lack APIs or implementation of them to properly sanitize: e.g.

⚠️ [last checked Nov 2024], Cookie Auto Delete even instructs it’s users to disable Total Cookie Protection - ⚠️ DO NOT DO THIS ⚠️

As of Firefox 86, strict mode is not supported at this time due to missing APIs to handle the Total Cookie Protection [… followed by instructions]
