I had one of my juniors who uses Firefox install Chrome to use those dev tools 4 months ago, because Firefox was just throwing garbage in the stack traces, while Chrome had transparent React code.

Not that it'd be a deal breaker for me, but he now debugs in Chrome when necessary, and still uses Firefox as his daily driver.

I'm sure there's something we could've changed for Firefox to work too, but for what it's worth we didn't do anything in particular for it to work in Chrome.

FWIW ff is my primary browser, I still turn to Chrome for debugging complicated js stuff.
