SetAsr I use Vanadium and block cookies
Vanadium is a (super duper) secure browser; it isn't an anonymous browser & GOS doesnt claim it offers anonymity. Youll actually look pretty unique, as there aren't many Vanadium users in the wild.
Browser anonymity is tricky. Tor Browser is really the only one that offers any level of anonymity - it makes all users look identical & randomizes your IP. Though Tor runs on Gecko, and will be much less secure than Vanadium
dhhdjbd Privacy guides .org is a good starting point
Second this. Youre confusing security, privacy, and anonymity. That'll make it hard to build a practical threat model. PG is a good resource to build those fundamentals
