Privacy means my data is private. I don't know if security implies privacy, in my mind I'm referring specifically to protection from direct threats to my device that aim to access resources that my browser doesn't expose (filesystem, elevated privileges and that kind of things).

That being said, my statement still stands. In that case, I can just summarize it as "I can't find a browser as secure as Chrome" (implying that yes, Brave and Vivaldi do the same, they are just less open about that)

If people can access resources you don't think your browser exposes, then in fact your browser does expose those things. You just didn't realize it.

Security does imply privacy, because one of the most important things in warfare is keeping information away from your adversary. If your browser is freely giving away information without a care in the world about who gets that information, then of course that information will end up in the hands of your enemies, and from there it can be used to do something you'd more readily recognize as a "security breach."

That is working around my intended meaning, it is not trying to build on top of it. The browser doesn't expose and allow writing to my filesystem indiscriminately, an exploit will allow that, but it's definitely not intended and that's what I'm referring to.
