Changes

IE11 features redesigned developer tools,[15] support for WebGL,[16] enhanced scaling for high DPI screens,[17] prerender and prefetch.[18] IE11 supports SPDY[10] on Windows 8.1 only.[19] In addition, IE11 supports Full Screen and Orientation APIs, CSS Flexbox and border image support, JavaScript enhancements, DOM mutation observers, Web Cryptography API, video text track support, encrypted media support and an improved HTML editor.[20]

Removed features

  • IE11 has removed support for document.all and attachEvent APIs.[20]
  • Quick Tabs (CTRL+Q)[21]
  • Work Offline command removed from File menu [22]
  • Drag and drop of selected content from IE to other programs like Word or WordPad

Performance

In one review, IE11 scored better than Google Chrome 30 and Firefox 26 in 2 of 4 benchmarks (including WebKit's SunSpider test), tied for fastest in a 3rd benchmark, and was last in Google's V8 performance benchmark. As a result of the speed improvements, the reviewer said "if you switched to Chrome for speed alone, you're now using the wrong browser."[20]

IE11 was also observed to use less memory with multiple tabs open than contemporary versions of Chrome and Firefox.[20]

User agent

According to MSDN on 25 July 2013, Internet Explorer 11 uses a modified user agent string that has the following general form:[23]

Mozilla/5.0 (Windows NT 6.x; Trident/7.0; rv:11.0) like Gecko

"x" in "Windows NT 6.x" token contains a different value, depending on the operating system version number on which the browser is running.

In comparison to Internet Explorer 10:

  • "MSIE 10.0" token is replaced by "rv:11.0"
  • "Trident/6.0" token is replaced by "Trident/7.0"
  • "compatible" token is removed
