I should mention, I'm currently using Firefox on Windows and Safari on macOS; Chrome is gone from my life. I
really like Firefox following their Quantum update; it feels super speedy!
But, I was kinda putting myself in the mindset of the GP. They're currently using Chrome's password manager, so they clearly prefer Chrome, and while Safari and Firefox have advantages, there's no overwhelming need for anyone to switch right now. For the sake of a democratized web, I hope that changes some day in the future.
