Back when I worked on websites (2011-2012), supporting IE6 through IE9 ate somewhere between 1/3 and 1/2 of all my development time, as nothing was consistent with any of them, and that included the same browser with slight tweaks. It was a horrible, time-wasting badly behaved set of browsers and because I worked on government sites for part of that, Internet Explorer support was mandatory. I'm so very glad they're gone - they were the lemon cars of the computer world of those days.
