What about developer tools? As a front-end dev I'm very pleased with the tools Chrome offers. I only tried Firefox's dev tools briefly but can they compare?
Their dev tools are comprehensive and have a very similar UI to Chrome. Personally, it wasn't hard to pick it up and I haven't (yet) run into any limitations.
Yes, they're mostly the same. On some points Firefox is better (e.g. DOM Inspector, Network tab, animations, dark theme), on others Chromium is (e.g. Profiler, sources). I use both.
