This means, never using a browser context you have ever logged into any service that is personally identifying. That also means the order in which you load pages. If your ritual is open pintrest followed by slashdot, that is now your finger print.
It isn't just what you do, but how you do it and the ordering between those events. You also don't want to accidentally deanon yourself or your peers, even when everyone is trusted because it also leaks group membership information.
The mental framework for opsec can be modeled as vector calculus and differential geometry. You have to think of the flow of information across a surface and in the integral of that flow. Assume an adversary with perfect total information.
