> For rust since it came from Mozilla team I'd expect by now Firefox is already re-written in rust by now but it seems yet to happen, and this article probably tell us why [2] Nope. In fact that article says: > By 2017, Mozilla had made two previous attempts to parallelize the style system using C++. Both had failed. And goes on to say how they were successfully able to re-write it in Rust, and then talks about the kind of security problems Rust solves and the ones beyond language scope (correctness). But I don't think we really needed an article to tell us why a 20+ year old browser that has a billion man-hours of development hasn't been re-written in a language that has only been stable for five years, and has a relatively small team working on it.
