Unfortunately console.log(foo) calls foo.toString() if and only if the console is open, and there is no way to disable this in Chrome or Firefox. Edit: You can redefine console.log to be a noop, but that's also detectable.

Theoretically you could also write a bookmarklet that could inspect or modify globals. Or a greasemonkey script.

      I stopped using them years ago for other reasons. We're talking about how to do research into their fuckery here, I'm not suggesting it's sane to fork a browser to make a company's crapware work.

I can't repro, how are you getting it to call toString?

  const foo = () => {} foo.toString = () => console.warn("called") console.log(foo)

This is not true, at least in Chrome. I've tried with an object with the `toString` property set, and tried with a function with an updated prototype. In both cases, Chrome just...displays the object.
