Curious, what makes you find those to be better than Chrome? I recently switched to FF for a variety of random work reasons, and found it so much worse than chrome (basic UI, dev tools, speed) that I switched back asap. Maybe I'm missing something awesome about them.

I use Safari, and I find it to be better than Chrome because it's easier to sync with my iPhone and iPad, and with iCloud keychain even my passwords are synced.

Interesting thanks

From the phrasing, I'm guessing this is more of a statement of values than a technical assessment.
