Maxthon (Chinese: 傲游浏览器, formerly named MyIE2) is a freeware web browser, created by JeffChen in Singapore.

[16][17] In 2002, current CEO Ming Jie "Jeff" Chen (Chinese: 陈明杰; pinyin: Chén Míngjié) created MyIE2 browser based on open source product MyIE.,[18] in Singapore, and renamed to "Maxthon" in 2003.

In 2005, the team received seed funding from venture capital firm WI Harper Group[19] and Morten Lund, the first Skype investor, and Chen moved the company to Beijing.

[23] In late 2010, Maxthon began releasing new compatibilities, including browsers for Android[8] Mac,[24] iPhone[25] and iPad.

[28] On April 10, 2007, TechCrunch reported that Google had invested at least US$1 million in Maxthon;[29] this was denied the following day by Chen.

[31] Maxthon Browser has received several awards and recognitions over the years for its innovative features and user-friendly interface.

In 2016, computer security researchers from Fidelis Cybersecurity and Exatel discovered the browser surreptitiously sending sensitive browsing and system data, such as ad blocker status, websites visited, searches conducted, and applications installed with their version numbers, to remote servers located in Beijing, China.

The researchers further found the data being sent over an unencrypted connection (HTTP), leaving users vulnerable to man-in-the-middle attacks.

Fidelis' Chief Security Officer, Justin Harvey, noted the data "contains almost everything you would want in conducting a reconnaissance operation to know exactly where to attack.

Knowing the exact operating system and installed applications, and browsing habits it would be trivial to send a perfectly crafted spear phish to the victim or perhaps set up a watering hole attack on one of their most frequented websites.

[64] Maxthon Passport allowed users to sign-in and register for free membership, and their avatar remains in that space for future visits.

[62] New features include:[65] On September 15, 2014, Maxthon released a beta version of a Windows web browser made for those with slow computers or internet connections.

[68] Aside from a series of new added and improved features, Maxthon 5 also introduces a few major built in functions, such as Maxnote as "your collecting button for the web", Passkeeper as "your smart password manager", and UUMail as "the guardian of your inbox".

[71] With the official release of Version 6.1.0.2000 Maxthon moved to a Chromium base,[72] but still support the dual Trident and Blink rendering engines.

Maxthon Cloud Browser for iOS saves and syncs key settings, content and features for users across multiple platforms and other devices.
