It's amazing how far apart I got from every single one of Mozilla's visions, from using Firefox as my main browser 8 years ago.
I love the fact that—as an example—as I travel Google shows me tools that I'll be interested in, like a currency converter, translate + word of the day in the local language, etc. etc.
I would absolutely hate having my main browser constantly forget who I am. I feel almost blessed every time I visit a website that I can log in with one click (or I'm already logged in), and when I sign up or buy stuff I can autofill my name, email, address, and credit card without having to start from scratch.
I'm not ready to give up extreme convenience and lots of time for the ideal of safeguarding my privacy with Google or Apple.
