Canonical's Rick Spencer has written about two small changes that are happening to Mozilla Firefox in Ubuntu 10.04
. The first is the default Ubuntu home-page with its search box in Firefox will now follow whatever the user has set as their default search engine in Firefox. The second change is that Canonical is changing the default search engine for Firefox in Ubuntu to Yahoo.
Google has always been the default search engine in Ubuntu's Firefox, but now it's changing to Yahoo beginning with Lucid Lynx. This doesn't have to do with Google's work on Chromium OS
or the Chrome/Chromium web-browser, but rather a business arrangement between Yahoo and Canonical. Canonical is changing the default search path over to Yahoo as the two companies have negotiated a revenue sharing deal off the advertisements when using Yahoo search on Ubuntu. Users can still switch Firefox to using Google search with a couple clicks, but Canonical is hoping this change will yield them some additional revenue.
This was made public today on the ubuntu-devel list
