That's good. So does every other browser since forever.
> when all other browsers break your code you will appreciate their hard work.
I am a webdev, and I use Firefox as my main browser for work. When I am done with a feature or a new page I usually test it in Chrome and it works without problems. Then IE, and I still have to tweak the hell out of the code to make it work there as well. So ms is not there yet.
When MS stretched violently with IE 6 back then, they changed the web landscape forever, they were light years ahead of competition. The practically invented AJAX. If MS can do with Edge what they did with IE 6, the future is very bright.
Since IE 6, most changes in web technology has been incremental. The powerful changes like WebGL are not enough mainstream. MS was, and still is, in power of forwarding things fast. So when you look at it like that, this is all good news.
