Yahoo is putting some site real estate behind its browser ally, Mozilla Firefox. At a variety of Yahoo sites (like Flickr) today you can see a small link at the upper right saying “Upgrade to the new Firefox.”

When you click the link you go to a Firefox download page that says: “Choose Independent. Choose Firefox.”

Mozilla and Yahoo announced a five-year partnership on November 19 in which Firefox will make Yahoo the default search engine in its browser — replacing Google.

Firefox users would be introduced to a “new enhanced Yahoo Search experience” starting in December, the companies said.

Firefox had used Google’s search engine since 2004, but when the renewal of the agreement came due this year the two companies parted ways.

The partnership between Yahoo and Firefox may end up helping both — and both need help. Firefox’s user numbers have been declining for years, and Yahoo search lags behind rivals Microsoft Bing and Google Search.
