Cross-site Request Leak Report
Google Chrome v62 (block third party cookies)

To evaluate whether your current browser instance's cookie policies can be bypassed with one of the request mechanisms, simply click on the specific instance you want to test. This will open a new tab, where the test is set up and executed: the test will try to initiate a cross-site request to cross-site.com. After a few seconds, you will be redirected back to this page, showing the results of the test.

To analyze the correctness of your browser extension, make sure to mark the checkbox underneath.
