Modern firefox is an awesome experience. The only reason I use Chrome is because the dev tools are that good.
Firefox: Nightly -> Developer -> Beta -> Stable -> Extended Support Release
Chrome: Canary -> Dev -> Beta -> Stable
I do remember back when I used chrome there would be new `console.x` features that were chrome only from time to time, but after I switched to FF I never really looked back
It's gotten a lot better over the last two years, especially when FF DevTools got support for source maps and TypeScript debugging, but it still lags enough to keep me using Chrome for my job, Firefox at home.
