2003年，当苹果决定在 Safari 中使用 KHTML 的时候，Mozilla 的 Mike Shaver 曾在博客中承认 Gecko 的缺点。 他同时预言，苹果会成为他们推广 Web 标准的联盟。

Why Apple rejected Gecko Gecko, which originated at Netscape and predates KHTML, is often criticized for its large and infamously complex code base.

KHTML was introduced to the world as part of KDE 2.0, a milestone release within the KDE community that included Konqueror, KDE's integrated KHTML-powered web browser and file manager.

Apple's code is being put to good use. Two of the KHTML developers have already merged in changes from Apple and the Konqueror 3.5 branch now passes the Acid2 test.
