Unfortunately, some researchers don’t understand the importance of making the code they use to reach their conclusions available.

QupZilla is a relatively new WebKit-based web browser written in Qt, which makes it perfect for KDE users. QupZilla looks just great, and it seems to be a perfect browser for those users who prefer a more different approach when it comes to the interface look and feel. QupZilla stands out with an interface that doesn’t resemble neither of the ‘modern’ ones like Firefox, Chrome or Opera, but rather keeps a classic look, which I believe may fit many users out there. So let’s see what this impressive browser is all about.
