Users will still be able to change which search engine is used when they perform a search from firefox, but with an estimated 25% of all internet users now regularly using firefox and users on average performing 30 internet searches a day the status of "default search engine" will result in increased traffic and increased revenue from advertising to whoever get's this place.
Plans are also being formulated to strike a deal that would insert Google adsense ads on to any page which currently contains no adsense ads. the ad-revenue from these adverts would more than likely be split 50/50 between Google and mozilla (i'm sure plugins will be available to block this function).
