Google Remains Default Search Engine at Firefox

Mozilla on Tuesday said that it has renewed a deal making Google the default search engine in the nonprofit organization's open-source Firefox Web browsing software.

"We're pleased to announce that we have negotiated a significant and mutually beneficial revenue agreement with Google," Mozilla chief executive Gary Kovacs said in a release.

Financial details of the deal were not disclosed. The agreement extends for three years Google's status as fallback engine for Internet searches made by hundreds of millions of Firefox users worldwide, according to Kovacs.

"Mozilla has been a valuable partner to Google over the years and we look forward to continuing this great partnership in the years to come," Google senior vice president of search Alan Eustace said in a release.

California-based Mozilla reported in October that royalties from nearby Google make up a large chunk of its revenue.
