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. Tencent rewrote the program again in 2008 and released version 4.0 on May 7. 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. At the same time, it also provides auxiliary functions such as mouse gesture and smart screen ads. Compared with Tencent TE, Tencent TT has added personalized functions such as software skin replacement. At this point, the software officially stripped from Tencent QQ and became an independent software. 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 (Tencent Traveler). 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. 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. This browser is one of the earliest page viewers in mainland China, rendering pages using the Trident layout engine (known as the Internet Explorer webpage renderer). On November 20, 2000, Tencent released the first version of Tencent Explorer ( Tencent Explorer, referred to as TE) and bundled it with the OICQ 2000 Preview1 1115 (now Tencent QQ).

Previously, Tencent had developed Tencent Explorer ( Tencent TE) and Tencent TT, two browsers based on the Trident engine, as well as QQ Browser versions 5 and 6, which integrated the WebKit engine. It utilizes two browser engines: WebKit and Trident.

QQ Browser is a web browser developed by Mainland Chinese technology company Tencent.
