Today, on things that only work on Chrome (or derivative) because your devs are fucken bastich, I give you:
Fedex payment - try to pay with Firefox on Linux and everything will be refused, with an unspecified "technical error" no matter what payment method is selected. Try to pay using Chrome on Android and, presto! Everything works!
Netdata with obvious display bugs in Firefox, while something based on WebKitGTK (Gnome Web) works.
I want things that work on ALL browsers, goshdarnit!!
