Make the Web Work for Everyone
Bravo! As a Firefox user, the trend of web developers only testing in Chrome (and ending up using features that only work in Chrome) is getting really annoying. Most of the time, the fixes are really simple, like including more prefixes than -webkit.<p>Very happy to see Mozilla raising awareness around this issue.<p>Personally, I have Firefox and Chrome open side by side for development. If those two work, Safari and Edge generally will too. I'll add IE specific rules/hacks afterward.
