I've downloaded and tried both Firefox for Linux and Windows.
When I have to use Windows, Firefox is my browser. When I use Linux, however, Opera is my choice. Regardless, both are much better than IE.
I'll be conducting a workshop on Internet security soon for my community association. All participants will get a CD with the latest version of Firefox for Windows (and I will probably include a second CD with a live Linux distro, too)
