I’ve finally moved all my machines to Mozilla Firefox 1.0. It is, by far, the best browser I ever used, and it is totally, truely free. Unfortunately, the French version is lagging behind a bit. Unless you are running something else than Windows, Linux, or MacOS, you have no excuse to use another browser. None.
Update: Sean asks why I switched away from Konqueror. The main reasons are XML support and Gmail. Gmail doesn’t support konqueror for some reason, and I badly need a browser having decent support for XSLT. Also, there is a comment below saying that Firefox is not stable on OS X 10.2.
