No, there are two types of rule in Cookie AutoDelete (CAD) that you have to read through their documentation to understand their function: Greylist and Whitelist. You have assign these domains to Greylist (whose filter setting has to be pre-configured first, namely you decide what to be kept/removed in greylist rule).

I use in combination with Firefox containers feature Enable Automatic Cleaning of CAD, which deletes all cookies (as well domain related contents) except those in whitelist. That has saved me a lot of time in manual greylisting.
