Especially heavy ajax sites like google mail and yahoo mail.  These two site fly!!  which is great because I’m on web mail all the time.  I’ve also noticed that all JS calls execute much faster, including some timer processes. For example, if you have a timed dynamically resizing window, it will execute faster. 

I also love how it imported EVERYTHING from firefox.  The only thing it did not get correct was the order of the bookmarks, but that was easy to fix.

I still have more sites to test, but so far, so good. 

Here is the link.  Go get it!
