`BrowserSniffer` is used to detect various aspects of the browser viewing the application. It was originally based on the [BrowserSniffer from Liferay Portal 6.2](https://github.com/liferay/liferay-portal/blob/6.2.5-ga6/portal-service/src/com/liferay/portal/kernel/servlet/BrowserSniffer.java). However, in Liferay 7, certain methods have been removed from the [BrowserSniffer](https://github.com/liferay/liferay-portal/blob/7.0.0-ga1/portal-kernel/src/com/liferay/portal/kernel/servlet/BrowserSniffer.java):{markdown}

Liferay Faces Util's `BrowserSniffer` should be consistent with Liferay 7's `BrowserSniffer`, so the following methods should be removed:

- `isWapXhtml()`
- `isWebKit()`
- `isWml()`{markdown}
