Mozilla clearly send data to Alphabet, googleanalytics and googletabmanager, I don’t believe that this data are only christmas greetings to the sponsor. But I also think and hope, that this will cese if Mozilla finish the contract with Google in 2024 as they say. Mozilla does not deserve to be under Google’s control and there are not many alternatives in the market.Yes, there are a lot of forks of Gecko and also Blink, but mostly with bad maintance, poor support or even contract with the devil, well with surveillance advertisings (Chrome, Edge, Opera (this one the worst)), with shady crypto companies (Brave), or direct filtering data to Gov and security services (Safari). Some exotics wit Qt or Goanna engine (Otter), batteling to survive or are discontinued.(Falcon) As said, Vivaldi and Firefox (or maybe one of the better forks, like Floorp or Midori), there are not much more.I’ve both.
