Browser sniffing (also known as browser detection) is a set of techniques used in websites and web applications in order to determine the web browser a visitor is using, and to serve browser-appropriate content to the visitor. It is also used to detect mobile browsers and send them mobile-optimized websites.
Modernizr uses feature detection, rather than checking the browser's property, to discern what a browser can and cannot do. It considers feature detection more reliable since the same rendering engine may not necessarily support the same things in two different browsers using that engine.
Web beacons embedded in emails have greater privacy implications than beacons embedded in web pages. Through the use of an embedded beacon, the sender of an email – or even a third party – can record the same sort of information as an advertiser on a website, namely the time that the email was read, the IP address of the computer that was used to read the email (or the IP address of the ...
Canvas fingerprinting works by exploiting the HTML5 canvas element.As described by Acar et al. in: [6] When a user visits a page, the fingerprinting script first draws text with the font and size of its choice and adds background colors (1).

Thus, layers could be used for browser detection. A JavaScript program would very often need to run different blocks of code, depending on the browser. To decide which blocks of code to run, a JavaScript program could test for support for layers, regardless of whether the program involved layers at all. Namely,
