I'm a big fan of firefox since 5 or 6 years now, especially since they remade their engine (around 2017) it's actually really good, also firefox sometimes provide tools for certains website ( like instagram and facebook ) to track you outside their website with Facebook container, i think they are a good choice if you want privacy, and it's doing just as good as google chrome, if you don't mind chromecast, it's the only thing that's missing between chrome and firefox imo
