Firefox

I get those a lot from other sites (weirdly YT Music doesn't on FF or Zen) like Amazon Music (even when just trying to buy a digital track or album). Weirdly the sites will act normal for a moment or two before removed about my browser not being "updated" or otherwise Chromium-based. We managed to break the internet being coded for IE, but allowed Google to openly make the new IE. Safari seems to work for some of the sites, but that is just because Apple made all the iOS browsers use Webkit with custom skins on one of the top selling phone/tablet options.
