Nice Description of Firefox ...

This browser "has been designed to make everyday tasks easier, provide dynamic security protection and improve the development platform and manageability. End user improvements include a streamlined interface, tabbed browsing, printing advances, improved search functionality, instant feeds (RSS), dynamic security protection, and more."

except it's for IE7 Beta!

All these features are already available with Firefox - and have been for some time! Which makes one wonder ... why wait for someone to play "catch up", when you can already be using them?
