I hear it’s the first browser in a long while to come with a new engine. Completely independent and no revenue model. To me that would work well for privacy but I see no mention of privacy as any benefit. In fact I don’t see a privacy policy anywhere !
Is a goal of the browser to be telemetry free ? Should I as a person who cares about privacy be showing any interest?


No, Rust doesn’t make your code more stable. It can help you making it more secure however.
Security and stability are related. They’re both about preventing unexpected behaviour.
