My use of Firefox has dwindled as I became frustrated at the browser freezing up at times. But I'm taking a new look, thanks to today's launch of Firefox 48, which will slowly introduce multi-processor support (i.e. one tab's misbehavior is isolated), a feature long available in my primary browser, Google Chrome. Also very important, and also under the covers, is the introduction of some components written in the new Rust programming language, promising great performance without the security issues of C++. Oh, and some new User Interface (UI) eye candy, which I could care less about.
