First, let's take a look at what is UA?
UA: It is a special string header that enables the server to identify the operating system and version, CPU type, browser and version, browser rendering engine, browser language, browser plugin, and so on.
IE11:IE11 will be Win8.1 's new Microsoft next-generation browser, which, in contrast to IE10, will also have a label sync option to reload the browse group on another Win8.1 device, in addition to the obvious speed and performance improvements.
As we all know, IE 11 changed the UA string, the new string is:
mozilla/5.0 (Windows NT 6.3; WOW64; trident/7.0; rv:11.0) Like Gecko
Because there is no "MSIE" string, then there is a "Gecko" string, resulting in many sites that IE 11 is firefox!
So there is the following embarrassing situation!
There are two ways to resolve this problem:
Method One: Set the compatibility view
Click the IE Menu "Tools" button and select "Compatibility View Settings". In the pop-up dialog box, add the Web site you want.
Method Two: Change the UA string for Internet Explorer 11
1. Win + R input gpedit.msc open Group Policy Editor;
2. Navigate to the Computer Configuration → admin template →internet explorer→ custom user agent string;
3. Double-click the open setting has started, the input string "MSIE 8.0";
4. Click OK;
5. Restart the browser to take effect.
