Well, when I installed that there ubuntu, it gave me Firefox 2. And for the first time in … I forget, but a matter of years, I have a firefox I can use to visit unknown/untrusted sites.
The big difference? Just one small but vital change. Disabling animated images works! It’s been broken in 1.x, leaving me with Konqueror as the only modern graphical browser that was actually usable. Now, finally, firefox makes the grade. And since it has the advantage that I can use it without installing the whole KDEboodle, I think I might make it my regular browser.
