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.
