Understanding this page
- What the tracker categories mean
What "advertising," "analytics," "social," "consent" and the rest actually mean for a company or a cookie, and how CookieTosser decides which one applies.
- First-party vs third-party cookies (and why "first-party" still tracks you)

- How to block or limit trackers
Browser privacy settings, content blockers, Global Privacy Control and clearing cookies compared honestly — what each one actually stops, what it doesn't, and what it costs you in return.
