Mozilla has announced that it has extended its search alliance with Google for at least three more years.

As per the terms of the agreement, Google will continue to be the default search provider for Mozilla Firefox.

Mozilla has not disclosed the financial terms of the deal .

The Google Search has been the main source of income for Mozilla,which accounts 84% of Mozilla’s $121.1 million revenue in 2010.

The original deal between Google and Mozilla got expired in November this year and in October Mozilla introduced Firefox with Bing, sparking rumors that Mozilla might switch to Bing as its default search provider.

This new additional three years agreement with Google killed such speculations and this shows that the rivalry between Google’s web browser Chrome and Firefox was not sufficient for a hurdle for these two companies to strike a deal again.
