This can only play out a few ways, right?<p>A) Firefox holds its ground, Advertisers hold their ground as well. Advertisers refuse to work with websites that support the version of Firefox with "Do Not Track", unless the websites add some code to tell their visitors to use another browser/refuse to load the site. This leads to two scenarios:<p>Ai) Developers agree and implement advertiser strategy, Firefox becomes an unreliable browsing experience, market share slips. Firefox possibly reverses position.<p>Aii) Developers refuse to implement advertiser strategy (by using either another ad partner or moving to a different monetization strategy), and advertisers finally reverse position.<p>B) Firefox holds its ground, advertisers cave: websites start seeing less revenue from ads as targeting isn't as effective anymore, websites that get most of their money from ad revenue either start panicking and blocking Firefox users, or start putting up paywalls.<p>C) Firefox yields, advertisers get their way: pretty much the status quo.<p>D) Firefox yields, advertisers yield: some sort of compromise between the two camps.
