Yahoo promoting Firefox and IE promoting Yahoo.... thats a bit strange

Recently it's been observed that Yahoo d been promoting Firefox 3 as its preferred browser and wanted users to download its customized version. This is evident as Yahoo might be thinking that Google would most probably focus on Chrome now than just Firefox as a result Yahoo can get its share from open source browsers like Firefox. as you can see below

But more interesting this we have observed when we starting using the latest version of IE 8. Here Internet explorer has given Yahoo search as the default search engine for search bar (see below) while Live search is second option. Does Microsoft still thinks that it will take over Yahoo ? That's in fact a reasonable question if we do not think that this is by mistake in case of IE browser.
Anyways the search battle field is becoming more and more interesting day by day as many other search engines are ready to take on their share. a few to mention are Cuil, Quintura and Clusty.
