Ok, i got a few more extensions:

Translate - thanks to Fencer,
MapIt - maps any highlighted address to mapquest.com
BugMeNot - if you don't know what that is, check out bugmenot.com website. That's a database of login/passwords for many websites that require free registration.

Also, i found that you can add your favorite search engine to that list in the right top corner. Good for people who want to have other than enlgish search.

I still think it's a little slower than IE if you hit some very slow server on the other end of the world. IE loads picture faster. But extensions functionality is awesome.
