Disappointing that Mozilla's CEO has chosen Reddit -- a platform that has grossly mistreated the volunteers who make it work -- as the venue to discuss the new anti-privacy tools that are turned on by default in the latest Firefox.

I hate to point to Reddit for that reason.

Mozilla has taken a bad turn, but you can (for now) turn off the latest on-by-default setting: In Settings / Privacy and Security un-check the “Website Advertising Preferences” checkbox.

@dangillmor and, if you're using and adblocker, none of your data is aggregated anyway, so it's the same as having it turned off
@scruss @dangillmor That’s only true to the extent that your ad blocker works, and they are never 100% effective 100% of the time.
@freeagent that's what the Mozilla CTO said in the Reddit thread tho
@scruss Yeah, they just didn’t clarify that ad blockers aren’t 100% effective all the time. Mozilla have built a feature here which is completely unnecessary for the preservation of privacy. In fact, to the extent that it does anything, it can only serve to decrease privacy. Ads can be served to users/browsers without any reporting back into a centralized database, which is what this does.
