Is the stuff not working in Firefox due to lazy devs too young to remember IE6?

  It's partly that, but it's also partly that the pace at which new standards of useful things get implemented (pre-ratification and post ratification) entails patchy support plus differing implementation decisions from under-specified standards. My favorite example area right now is all the fun that is CSP. Firefox supports the SecurityPolicyViolation Event, which is useful so that you can let non-power users know about CSP issues without having to open the console, except it's gated by a setting in about:config that is off by default. Additionally for CSP's report-uri endpoint, Firefox won't send up any cookies with a request to that endpoint (https://bugzilla.mozilla.org/show_bug.cgi?id=1506992 https://bugzilla.mozilla.org/show_bug.cgi?id=1506992) which sucks if the endpoint relied on authentication that way. Chrome just works, meanwhile, on both of these issues. (Of course personally, if something doesn't work in Firefox, then I just don't use that something, or if I really need to (e.g. test business feature), I use chromium for just that one thing.)
