QQ Browser
QQ Browser is a web browser based on the Chromium engine developed by Mainland Chinese technology company Tencent. It utilizes two browser engines: WebKit and Trident. Previously, Tencent had developed Tencent Explorer and Tencent TT, two browsers based on the Trident engine, as well as QQ Browser versions 5 and 6, which integrated the WebKit engine.
History
On November 20, 2000, Tencent released the first version of Tencent Explorer and bundled it with the OICQ 2000 Preview1 1115. This browser is one of the earliest page viewers in mainland China, rendering pages using the Trident layout engine.The first version of Tencent TE includes the "Who is with me" feature, which allows OICQ users who are browsing the same web page to communicate online, but this feature raises users' concerns about personal data security. In order to eliminate user concerns, Tencent issued a statement on April 24, 2003, stating that browsing the webpage does not reveal personal data when using this feature; if users do not want to use this feature but also want to use the browser, you can choose "Invisible" mode.
In 2003, Tencent rewrote its source code on the basis of Tencent TE, and released the first version of the new browser on November 11, Tencent TT. At this point, the software was officially stripped from Tencent QQ and became an independent software. Compared with Tencent TE, Tencent TT has added personalized functions such as software skin replacement. At the same time, it also provides auxiliary functions such as mouse gesture and smart screen ads. But the "Smart Shielded Ads" feature records the content that users browse online, and stores the records in the TTraveler2.dat file in the software installation directory.
Tencent rewrote the program again in 2008 and released version 4.0 on May 7. From this version, TT opens the web page and browses it in multiple threads to improve speed and performance, but still centered on the Trident layout engine. The final version of the 4.X series is the 4.8 version released on January 5, 2011.
