> many high quality sites are tested using automated testing suites (through Selenium, or otherwise) Big sites like Google* and Facebook* work less and less reliable in IE11 (UI glitches, JS errors, CSS position issues). As almost all of their developers use OSX or Linux and most of the tests run on Firefox and Chrome, it's hardly a surprise. I loved IE since version 3 because of its native UI and its responsiveness, but as there will be no IE12 I will move on as well. Well, Microsoft could open up their browser engine "trident-edge" like they do with dotNet vNext. * Google.com frontpage shows a unformatted sentence on top left corner for ca. 1 seconds, it seems like a JS loading race-condition. Every other week on FB a few minor features like selecting posts privacy groups are broken for a day or two. The React based search is unstable/broken on Android 2.3 as well, before that the mobile web version stayed already completely unchanged from 2010 to 2014. I don't want to blame them, as I guess the majority of users uses their apps and Chrome/Firefox.
