After I moved to 8.04 I found Firefox incredibly unstable. I couldn't
even save bookmarks between sessions. I have used Opera many times over
the years but not solely until recently. I have almost no problems with
it. As a browser is perfectly fine. The few problems I have had I'm sure
is because of my upgrade to 8.04 but on my earlier setup, Feisty, it ran
perfectly.

The only thing that I give it a mark against is when I'm developing for
the web. The development tools suck.
