Let&#x27;s say the first domino falls and they decide to sell. Next Google buys them and converts all Yahoo! search traffic to Google search traffic. That leaves Mozilla in a really odd spot. Most of their revenue comes from Yahoo! so they would eventually have to either go back and make a deal with Google or move over to using Bing as their default.<p>Search engine competition gives Mozilla an upper hand at the bargaining table, this could be not great for them.
