Maxthon (, formerly named MyIE2) is a freeware web browser, created by JeffChen in Singapore. It is available for Windows, macOS, Linux, and as Maxthon Mobile for Android, iOS, and Windows Phone 8. Since version 6, Maxthon is based on Chromium.

Overview
Maxthon is a Hong Kong company known mainly for producing web browsers for Windows. It is headquartered in Singapore, with offices in Beijing, Hong Kong, and San Francisco, US. Most of Maxthon's engineers are based in the corporate headquarters in China, which develops and maintains versions of the Maxthon browser for Windows, macOS, Android, iOS, and Windows Phone.

Maxthon has also created other products including a Chinese language news and information portal i.maxthon.cn, a Chinese language casual gaming portal and humor website, a ‘Kid Safe’ web browser for Android and iOS, a free online account system named Maxthon Passport, and an English language news and information web portal i.maxthon.com.

Corporate history
In 2002, current CEO Ming Jie "Jeff" Chen () created MyIE2 browser based on open source product MyIE., in Singapore,  and renamed to "Maxthon" in 2003. In 2005, the team received seed funding from venture capital firm WI Harper Group and Morten Lund, the first Skype investor, and Chen moved the company to Beijing. In 2006, Maxthon received further investment from the US-based venture capital firm Charles River Ventures.

Maxthon was one of the twelve browsers Microsoft presented in 2010 at BrowserChoice.eu, a website allowing users of Windows residing in the European Economic Area to choose which default web browser to use on their computer. In late 2010, Maxthon began releasing new compatibilities, including browsers for Android Mac, iPhone and iPad. As of August 2012, Maxthon is still in the first tier of browsers in BrowserChoice.eu after the removal of Apple Safari. The Maxthon Cloud Browser was released on December 10, 2012.

Investment from Google 

On April 10, 2007, TechCrunch reported that Google had invested at least US$1 million in Maxthon; this was denied the following day by Chen. However, in an interview with the Chinese web portal Sina.com, Chen did not rule out future "cooperation" between the two businesses.

Awards 
Maxthon Browser has received several awards and recognitions over the years for its innovative features and user-friendly interface. Some of the awards and recognitions include:

 WebWare 100 Winner : Maxthon was selected as one of the top 100 web applications by WebWare 2009, a CNET site.
 About.com Reader's Choice Awards (2009, 2011,2014): Maxthon was voted as the Best Alternative Browser by the readers of About.com in both 2009, 2011 and 2014.
 Red Herring 100 Asia (2013): Maxthon was included in the Red Herring 100 Asia list, recognising the most promising private technology ventures from the Asian business region.
 PCWorld's 100 Best Products of 2011: Maxthon was ranked among the top 100 products by PCWorld magazine in 2011.
 Global Mobile Internet Conference (2012): Maxthon Mobile was awarded the Best Mobile Browser at the Global Mobile Internet Conference held in Beijing, China.
These awards showcase Maxthon Browser's commitment to innovation and user experience, even though it has not reached the same market share as some other major browsers.

Data privacy issues
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. According to Maxthon, the data is sent as part of the firm's 'User Experience Improvement Program' and it is "voluntary and totally anonymous." However, researchers found the data still being collected and sent to remote servers even after users explicitly opt out of the program. 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." Maxthon CEO Jeff Chen claimed that this was due to a bug that was fixed as soon as Maxthon was made aware of the issue; however, Exatel had notified Maxthon of the issue without getting any response.

Software

Development history
According to Maxthon International CEO Ming Jie "Jeff" Chen, Maxthon was based on MyIE, a popular modification created by Chinese programmer Changyou to customize Internet Explorer web browser. Changyou posted most of the source code for MyIE on his Bulletin board system before leaving the project in 2000. Chen then continued independently developing MyIE and in 2002 released a new version, MyIE2. Users around the world were quite active in contributing to MyIE2's development, adding many plug-ins, skins and assisting with debugging. MyIE2 was renamed Maxthon in 2003.

Maxthon 2 was introduced in July 2007, and Maxthon 3 was released in September 2010. Later that year, Maxthon began introducing browsers for portable devices. In December, Maxthon for Android was released. On July 7, 2012, Maxthon for Mac was released, with Maxthon for iPhone and iPad released in August 2012. On December 10, 2012, Maxthon Cloud Browser, also named Maxthon 4, was released.

Features
Maxthon 5 introduced these features:

 UUMail: enhances the email experience by creating unlimited virtual email IDs to keep the real email address safe and filtering out spams to make sure the inbox stays clean and organized.
 Maxnote: the original 'Favorites' feature upgraded to 'Maxnote'. Users can collect everything, read anywhere, and record anytime.
Passkeeper: help users remember all passwords securely and smartly. Synced users passwords to the Cloud and then accessed on all different platforms & allows people to add and edit "Accounts" and "Private Notes". It also helps users to auto-generate random complicated passwords when registering on a website so there's no need to worry about passwords being cracked anymore.

Browser versions

Version 1.x
Maxthon version 1, which continued version 0 of MyIE2, was an Internet Explorer shell that implemented a tabbed browser using the Trident web browser engine which Microsoft introduced with Internet Explorer 4. As such, version 1 was compatible with every version of Windows from Windows 95 to Windows 7. Development of version 1 stopped in 2010 with the so-called Maxthon (Classic), version 1.6.7.35; earlier releases are available from Maxthon, and version 1.6.7.35, which fixed a bug in selecting the default search engine, is still available at other download sites.

There are many add-ons available for Maxthon Classic, and more are available through discussion forums. Specific threads may provide direct download links also.  Some add-ons are build-specific, but in that case, a clear indication of compatibility can often be found.
