I just downloaded it and installed it since my last post. Seems to work ok. I don't notice any speed difference over firefox, which I normally use.
Why would you delete Opra to install firefox? You can use them all.
Like I said, I did not like the email in Opera. I used to use Netscape and like the interface but could not upgrade to XP service pack 2 because Netscape simply stopped working.
Opera's email just seems a little more clugy then thunderbird.
I also have IE that comes with the computer so I did not see the need for three browsers.
