I use uBlock Origin and make some changes to the default settings. Have seen recommend configs, but haven’t gotten to implement them yet.

What do you do to make Firefox even more privacy respecting and secure?

    • Canvas blocker - prevents some usage of javascript for fingerprinting.
    • Change Geolocation - the actual reason that I use it is not privacy, but to prevent Google from forcing local results (I set my geolocation to Antarctica). However you can use it for privacy, specially if you live in a small town.
    • Decentraleyes - prevents tracking through content delivery.
    • Ninja Cookie - handles cookies banners, telling them that you don’t allow cookies. It’s one of those extensions where QoL is privacy, since those banners are often crafted in a way to tire you out so you allow cookies.
    • uBlock Origin - I guess most people here know about it.
