Sometimes IE is faster... but there are some tweaks you can do that makese it seem like Firebird is faster. It can be set to start rendering the page as soon as it gets something where with IE, it waits till it has the whole HTML file first... not a huge speed diffrence but a little. Of course sometimes Firebird could be slower... it is however just a work in progress right now. There is no "final" product.

It's what they call, a "technology preview". It's basically still Beta... and for a beta it's pretty damn good. There are little things here and there that need work... however... realize that it's almost to the usable point that IE is, and it's still beta... IE has been around for.... how many years now?
