There is value from seeing which result a user apparently likes best, which lets you train your search engine better. But Google already has a ton of this and the marginal contribution from Firefox users must be minimal. Instead, probably a different, smaller, search engine would probably pay. Though, even then, simply the cost of serving acceptable search results could be higher than the marginal value of the data? Either way, this goes from a contract bringing in hundreds of millions to maybe tens at best?
