For instance I clicked on the Blob line and the code looks to fetch and URL with a Blob encoded and fetches it again? There is so little context to say what is really wrong... or if there is anything really wrong.
I looked up Blobs myself and read through the specs on MDN and I just dont see a problem.
In the Blob case: the test code is storing a unique string in a Blob URL under one website (first party), and then attempting to read back that string under a second, different website. (See "result, different first party".) If the string is accessible under a different first party, then it is possible to use a Blob URL to track a user between two different websites.
Just some verbiage on each test would be wonderful.
You have clearly worked on it. It is a really good resource.
It was helpful feedback. I value all critiques because they help me make the site better.

There is some explanation for each test, if you click on the test name. But it's clear I need to expand those explanations and also make them easier to find.
