I hit a few in the past. But, I'm failing to find any of them at the moment... Maybe I should give Firefox mobile another try.

It could be that my baseline was the Chrome rendering, so any discrepancy was classified as "it's broken".

Adblock on a mobile browser is a gamechanger. I wouldn't go back even if a quarter of sites were broken on FF mobile (and they aren't, I've been using it for 2 full years desktop and mobile, and only found a single compatibility issue - a restaurant's take-out ordering page)

Honestly, in this day and age, any discrepancy from Chromium/WebKit is probably broken. But if we're talking about a few pixels' difference here and there, plenty of sites are more broken than that on every browser.

I have encountered a couple of (financial, natch) sites that insist on a Chromium-based browser in order to do vital operations like download statements. Switching browsers for those few exceptions is annoying, but not a deal-breaker (for me).

Have you tried a user-agent switcher? I think you can even set them up to always have a specific agent depending on the domain. Chances are, they don’t need chromium, they are just written by (even more than you’d think) incompetent people.
