Understanding this page
- How to see which cookies and trackers a website loads
A hands-on walkthrough for checking what a site sets before you've clicked anything, using Chrome and Firefox's built-in tools, plus how CookieTosser automates the same check every month.
- What counts as valid cookie consent in the EU

- Consent management platforms explained
What a CMP banner is actually doing behind the scenes, how the IAB's TCF standard and Google's Consent Mode v2 fit in, and why a banner being present is no guarantee that nothing loads before you answer it.
