I'd like a fork of chrome which removes all (or at least most) the "features" mentioned - a browser that renders well but just doesn't support these masses of unsecure features.

If you want to give 3rd parties access to all that stuff, you can run chrome. But I don't - I want the bare minimum that will run normal websites. I know that will break some pages, I'll accept that. (And that would give me a smaller & faster browser.)
