The big one for me is that Chrome's JavaScript engine is much faster than Mozilla's. I'm not sure why, but it makes a noticible difference.

I use this to my advantage by using FF as my daily driver. I believe that if my site is fast on Firefox, then it's damn near fast enough for everyone.

I ran into an interesting situation where I was building a Conway implementation and getting 60fps in Firefox / 10fps in Chrome. Turned out that Chrome had absolutely horrible performance with attempts to access out-of-bounds array indexes, where Firefox had some early fail fasts in place.

So anecdata, but I wouldn’t rely on Chrome automatically working well if Firefox does.

Lots of web devs only testing in chromium browsers, perhaps?

What we do at my company is I only test in Firefox, another developer only uses Chrome, a third only uses edge and QA tests on Safari.
