Do you use content filtering / ad blocking technology in conjunction with Safari? Last I tried to use Safari, it seemed some of the most common tools could not be plugged in / added on to the browser.
Safari 13 eliminated the previous extension scheme. So there’s no more uBlock Origin and similar blockers (there are content blockers, which work differently from uBlock Origin). Since the ad blocking extensions are lists of content to be blocked that’s given to Safari, one is better off using NextDNS or pi-hole for blocking ads (these will work across all apps too).
Wipr is great. Both iOS and MacOS. Safari + keychain is unbeatable IMO. I tried onePassword and I use Brave for dev (Chrome has too much CPU usage, and firefox for Grid debugging). I run Brave / Safari / Chrome / Vivaldi. I find myself in Safari most outside of Dev (zero inside dev).
