I chose to only review the GUI web browsers, since it's not exactly appropriate to compare a text-based browser like Lynx with Opera, for example. The browsers reviewed are the latest ones included in Debian Lenny, current date (May 17, 2008). The system used to review them is a Intel Core 2 Duo 1.8 GHz with 1 GB DDRAM2. The comparison includes the major five Linux browsers: Konqueror, Firefox, Opera, Epiphany and Galeon. I'm aware of others like Dillo or the older Mozilla, but decided to include only the big players at the moment.
Konqueror is the KDE web browser. Actually, it's a web browser among many other things like file manager or image viewer, but that is not the object of this review. Konqueror uses KHTML as a rendering engine. It has some problems displaying some pages or submitting certain forms.
