This morning was the first time I had heard “Internet Explorer 11” even mentioned. Microsoft released the first platform preview of Internet Explorer 10 a mere four weeks after the release of Internet Explorer 9, so it wouldn’t surprise me at all if IE11 was already starting to make an appearance in some form.

The new upgrade to Windows 8 – dubbed Windows Blue – was leaked on the Internet recently which revealed Internet Explorer 11. It was also discovered that its user agent will mimic that of Firefox. Interesting.

Mozilla/5.0 (IE 11.0; Windows NT 6.3; Trident/7.0; .NET4.0C; rv:11.0) like Gecko

Above is the reported user agent string. I have only seen it in a screen shot so I apologize for any typographical errors.

It’s theorized Microsoft is going down this route to avoid browser sniffing and having a different CSS style sheet served because it’s Internet Explorer and not one of the standard compliant browsers. See what I did there?

I think it’s a little too early to tell what the final user agent string will be for Internet Explorer, and for all we know this could be completely false or fake, so I’m going to withhold any judgement until there’s at least a platform preview available. The browser though appears to be in its infancy since the only information I can find about it on the Internet is related to the Windows Blue leak and its user agent string. Or maybe Microsoft is keeping a very tight lid on it. We shall see.
