I tried to switch two years ago, but back then Firefox was very resource hungry on my MBP so I stick to Safari. Chrome - with Google‘s approach to privacy - was no option at all, even if their browser was magnitudes better (which it was not; the differences are marginal in my perception). A few months ago I tried FF again. This time I was amazed. No CPU spikes. Super fast startup. - I cannot explicitly express my arguments and my sentiment, but my gut feeling says that Google‘s approach to privacy is totally wrong. So I don‘t want to touch any of their products. That‘s why I migrated my emails to fastmail.com, am using duckduckgo.com instead of Google.com, switched to Firefox from Chrome, to Dropbox from Google Docs. Abandoned Google Photos.
