Ie 11 Browser Recognizes Itself As Mozilla

I am working on MVC application, .net 4.5 framework, VS 2010. I have a piece of Javascript code that identifies which browser the application is running. If the browser is Firefox

Solution 1:

Yes. IE 11 doesnt say it is IE anymore, it says it is Mozilla.

Althoug, all IE versions respond the word Trident (its layout engine) in all of its versions.

So something like this could work in your javascript

<scripttype="text/javascript">CheckIE();
    functionCheckIE()
    {
    varBrowser;
    Browser = navigator.userAgent;
    if (Browser.indexOf("Trident") == -1)
    {
        //WHATHEVER YOU WANT IF IT IS NOT INTERNET EXPLORER
    }
    }
</script>

Solution 2:

Yes, it does:

The compatible ("compatible") and browser ("MSIE") tokens have been removed.

...

These changes help prevent IE11 from being (incorrectly) identified as an earlier version.

Still there are some ways to detect it (search for "How to detect ie11"), but your best bet is to remove browser-detection code at all.

Solution 3:

This is because IE 11 has a different style of user agent strings then previous versions of IE

http://msdn.microsoft.com/library/ms537503.aspx

User-Agent: Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko

Solution 4:

Take a look at User agent string of IE 11: http://msdn.microsoft.com/en-us/library/ie/hh869301(v=vs.85).aspx

Now it says:

Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko

I think that this is the reason.
