No, I'm not doing it!
Microsoft stopped supporting these browsers January 12th 2016. I am not going to bend over backwards to support a browser that isn't even supported by the company who made it.
Like IE6, IE 8, 9 and 10 were horrible browsers. IE 11 isn't much better, and although I can't say I like Edge - at least it attempts to support modern standards.
My efforts will be spent making my software compatible with the major supported browsers. IE 11, MS Edge, Chrome, Firefox, Safari and Opera
