Forget IE7, FF2 more than makes up for it. This new version is prettier and has new features coming out of its nose. IE had the upper-hand in certain areas for a little while, but FF 2.0 is the best browser ever.
For example, you will see less spelling errors in this blog from now on, because FF 2.0 has a built-in spell-checker. Result.
Incidentally, I have found out why IE blurs the internet and how to stop it doing it. It's a new rendering something or other which they have enabled by default and you just have to switch it off.
