IE10's Browser Mode setting under Developer Tools seemed to be extremely useful. I cannot find it in IE 11. Does the option still exist? If so, where?

It is possible to bring them back by editing registry: stackoverflow.com/questions/17871124/… – user241748 Jul 29 '13 at 21:54
    
A shame that they removed one of the more useful functions IE had over other browsers. Yet another reason to go with a non-IE browser - particularly with regards to development. Thank you so much for all the responses. It's very hard to pick a winner but I've gone for the selected answer based on community votes. – ForTheWatch Dec 6 '13 at 10:18

It's gone. There's an underwhelming Emulation tab, but the ability to emulate old IE versions has been removed.

As this page states, "If you need to test webpages in older versions of IE, check out Modern.ie for testing tools, including virtual machines that run older versions of IE in appropriate versions of Windows."

I'd suggest downgrading back to IE10: wikihow.com/Uninstall-Internet-Explorer-11-for-Windows-7 – wings Sep 17 '13 at 18:55
    
@wings this option is not showing in my PC screenpresso.com/=FDyO I upgraded from Win 7 to 8.1 – metal gear solid Nov 1 '13 at 13:13

In the latest update to Windows 8.1 the IE 11 F12 developer tools you can set the document mode to; 5, 7, 8, 9, 10 or Edge (11) mode from the emulator tool. The feature wasn't in earlier builds.

For some users (such as myself - lucky me) the Browser Mode and the User agent string dropdowns are both blank. This is really annoying as I do need to constantly test in various modes (I do developer support so this is crucial to me.

Thus far, the best answer I could find was on answers.microsoft.com ... the suggestion there was to create a new user profile... Others said that worked but in my opinion, this is as much overkill amputating your leg to address an ingrowing toenail.

I just wanted to throw this out there in case others find this post (as I did) while looking for the answer to why is this blank)

It has gone (at least, gone for now). In the future they may bring it back but until then, you have 2 options

This can be done via a registry hack as shown here (as per comments in OP by eug1111)
