Maxthon (, originally known as MyIE2) is a freeware web browser for Windows, OS X and Linux, developed by Chinese company Maxthon Ltd based in Beijing. It is also available on Windows Phone 8, iOS and Android platforms as Maxthon Mobile. Since the release of version 3, Maxthon supports both the Trident and the WebKit rendering engines.
Maxthon won CNET WebWare 100 Awards in 2008 and 2009, and was #97 in PCWorld's list of the 100 Best Products of 2011. In July 2016, concerns were raised regarding the browser's security weakness, when it was found out by cybersecurity experts that it sends "ad blocker status, homepage URL, websites visited by the user (including online searches), and installed applications to a server in Beijing, China" via HTTP, leaving the user information "valuable for a malicious actor looking to conduct a targeted attack."
