A browser can see and collect sensitive data (the sites you visit,autofill data,location,device info,download history,ad history)
Your browsing history in particular can reveal a lot about you.
Through this collected information, you can end up profiled on things like:
Political views
Sexual preference
Health status
Economic status
Career status
The goal of this list is to limit what gets collected by blocking tracking domains (for more security and privacy, I'd recommend using a privacy-focused browser that doesn't track you, like DuckDuckGo).
Note: whenever the domain list is pasted as text (in the post body or in a comment) Reddit's filter auto-removes it. Because of this, I'm sharing the blocklist as a raw link in the post body instead.
Raw links:
For basic list:
325 domains
For aggressive list:
351 domains (26 additional aggressive domains on top of the basic list)
For anyone who wants to see the full research and infrastructure mapping for each provider:
