SharkLaser writes: Mozilla's future looks uncertain. Last week Chrome overtook Firefox's position as the second most popular browser, the new versioning scheme has aliened most Firefox users and now advertising deal between Mozilla and Google, the one that almost fully funds Mozilla's operations, is coming to an end. One of Firefox's key managers, Mike Shaver, also left the company in September. "In 2010, 84% of Mozilla’s $123 million in revenue came directly from Google. That’s roughly $100 million in funds that will vanish or be drastically cut if the deal is either not renewed or is renegotiated on terms that are less favorable to Mozilla. When the original three-year partnership deal was signed in 2008, Chrome was still on the drawing boards. Today, it is Google’s most prominent software product, and it is rapidly replacing Firefox as the alternative browser on every platform.". Recently Mozilla has been trying to get closer with Microsoft by making a Firefox version that defaults to Bing. If Google is indeed cutting funding from Mozilla or tries to negotiate less favorable terms, it could mean Mozilla's future funding coming from Microsoft and Bing.
