Fennec doesn't have any of it (Google Analytics, Pocket, Mozilla Tracking), which is why it's my choice of mobile browser. It's on FDroid
We already live in hell and there's no upper limit on the thermostat.
Well actually there is because the smart thermostats are getting remotely limited by power companies sometimes.
At least on android Firefox has Google tracking built into the app among much other tracking/ads. If you don't like Brave you may want to consider a Firefox fork. On IOS Brave is the only big browser with competent adblock afaik until/unless Firefox gets extensions going.
Edit: I forgot criticizing Firefox is wrongthink on the fediverse and will get you donwnvoted no matter what. Even if it's in the context of advising people to switch FROM Brave TO a Firefox fork on Android.
