Firefox maker Mozilla and Google have renewed their search engine partnership deal for the next three years.
The open source outfit said in a statement that the search deal, which ensures that Google stays as the default search engine of the Firefox web browser, brings considerable amount of revenue to the company.
Firefox comes with its own search tab which lets users search multiple search engines from their existing page or by opening a new tab without having to visit the website. The browser comes with support for multiple search engines like Bing, Yahoo, Wikipedia and Ask.com but Google remains as the default search engine.
"We're pleased to announce that we have negotiated a significant and mutually beneficial revenue agreement with Google. This new agreement extends our long term search relationship with Google for at least three additional years," Mozilla said in a statement.
The companies failed to reveal the financial details of the deal as they were bound in confidentiality agreement. Google is the biggest source of revenue for Mozilla, accounting for 84 percent of Mozilla's revenue in 2010, which was at $123 million.
