"Many KDE users tend to take the Konqueror Web browser for
granted, but that's a mistake. Konqueror may not be able to replace
Firefox as a Web browser for every site, but it does a lot more
than just simple browsing.
"About 95% of the sites that I visited look and feel exactly the
same in Konqueror as they do in Firefox, but a significant number
of 'Web 2.0' sites do not work or have some missing functionality.
On the Netflix site, for example, in Firefox, you'll see an
additional information overlay when you hover the mouse over a
movie thumbnail, but in Konqueror nothing happens. When using
Konqueror with Gmail, you'll be redirected to the plain HTML view
of the site--which is adequate, but not quite as useful as the
AJAXified version that works so well in Firefox. The Yahoo!
homepage rejects Konqueror, suggesting that you 'upgrade' to
Internet Explorer, Firefox, or another supported browser, but if
you set the browser identification to Firefox, Yahoo!'s home page,
Yahoo! Mail, and My Yahoo! pages work just fine..."
