Mozilla has extended its search partnership with Google for at least three additional years, the company has announced.

Under the terms of the agreement, Google will continue to be the default search provider for Mozilla's web browser, Firefox.

The financial terms of the deal were not disclosed.

The Google Search deal has been a key source of income for Mozilla, generating 84% of Mozilla's $121.1 million revenue in 2010.

The original deal between Mozilla and Google expired in November 2011, and in October Mozilla launched Firefox with Bing, sparking speculation that it might switch to Bing as its search provider.

The new multi-year arrangement with Google squashes such rumors and shows that the rivalry between Firefox and Google's web browser Chrome wasn't enough of a hurdle for the two companies to strike a deal again.
