I dev with Chrome for the dev tools and use firefox for literally everything else, the Tab containers thing was the latest in a long sequence of "man they make that so much easier than Chrome" features.

Used both for a long time.

I'm okay with the dev tools in either. Install the React dev tools addons in both browsers and you're basically 99% of the way there =P

(I like chrome's mobile 'simulation' better, but both still lack lots of things I wish I could do, like simulating tiny CPUs or limited RAM, actually tracing through setTimeout, etc)
