Waterfox is Firefox with all the telemetry shut off.
I have a tutorial for anyone that doesn’t use the terminal much to install Waterfox I modified from a regular tutorial:
Waterfox will update by itself. When a never version is released you don’t need to run the tutorial again. Just download it, get it to opt, extract it in opt and delete the old Waterfox folder.
It for sure has AI on mobile app - right next to search bar it asks if you want to use Duck.AI - don’t know if it’s implemented in a browser for desktops though as mobile one is an app separate from Firefox
