Firefox, you're supposed to be in my pocket, not the other way around
Everyone saying "oh, just right click and remove it; it's so easy" is entirely missing the point. The simple fact is, Mozilla took a third-party, proprietary service and bundled it into the browser. If this becomes the new norm, imagine downloading Firefox v53 and having six different services installed (all consuming memory, collecting personal data, etc.) all because some research studies they collected said "people like this." Sure, every subset of the population is going to like different services. When I download Chrome, I install PushBullet, Disconnect, the Chromecast extension, and Ublock. But that doesn't mean that every other users wants or even needs those same things. The entire purposes of add-ons is that they can be... added onto the default experience. Mozilla has now begun changing the default. While they may claim this was done "purely for the benefit of users," it sure smells like it was done for money.EDIT: for anyone who doesn't think it wasn't about money, please explain why it is so difficult to remove, why I have to open about:config to "disable" (not remove) it, and why it wasn't just added as an add-on (which already existed)?
