It is a million times easier to avoid AI on browsers that simply do not use it, or that make it a fully opt-in feature, than to use an AI browser and then need to opt out. I have been a fan and user of firefox for many years and recommended it to many others, but if it becomes an opt-out AI browser I and many others will be leaving. This is not only frustrating to the users who need to move, but an unfortunate step backwards for the browser that has garnered a good reputation and dedicated userbase. How can we stop firefox from adding AI features, or at the very least make them Opt-in?
