@AskPippa @briankrebs Honestly, Firefox is pretty light on data collection, and unlike Chrome's Omnibox (idk if that's still what they call it, but the functionality is still there) you can easily opt out of all of it, so you really don't need any extensions to protect you from Mozilla themselves, and you can just as easily use a fork that removes telemetry, but there's so much more data collection and tracking just out on the open internet, so something like Privacy Badger most definitely wont hurt, and while I'm always weary of even privacy-focused products when they don't charge for their work (am I the product?), the fact that it's from the EFF makes me feel pretty good about that one. I don't actively use it, but I do have Firefox's (Waterfox in my case, but it's a stock feature) built-in Tracking Protection (see attached).
My beef with Firefox is less that I feel my browser is spying on me, and more that Mozilla's actions are increasingly misaligned with their own mission statement, in a way that makes me feel that one day in the future, they will completely alienate their comparatively small but committed userbase, and the only real browser vendor left will be Google (and that truly terrifies me).
