High Quality Content by WIKIPEDIA articles! Classilla is a Gecko-based web browser for PowerPC- based classic Macintosh systems, essentially an updated descendant of the now-defunct Mozilla Application Suite by way of the Mac OS port maintained in the now-aborted WaMCom project. The name is a portmanteau of Classic, and Mozilla. Like the Suite it is descended from, Classilla offers E-mail, Usenet, Gopher, FTP and World Wide Web access, using a modified version of the Gecko layout engine called Clecko. Classilla also includes its own versions of the DOM Inspector, Mozilla Composer and Venkman components; the former IRC ChatZilla component was removed in version 9.1.
