Just want to put here that if you're using a Mac and haven't tried Safari recently, you're missing out. A few things: - Battery life is fantastic compared to Chrome/FF - Privacy seems to be top-notch - The tab ordering situation is now chrome-like (my biggest gripe in older versions of safari) - Experimental features are 1 click away, easily enable/disable WebGL2 - Support for the WebExtensions standard means addons…
Not sure if they fixed this in Big Sur, but since Mavericks all the way through Catalina there's been a critical bug with Safari's use of the macOS keychain, such that if you don't use iCloud Keychain, then you cannot migrate your Local Items keychain (the one used by Safari) to another machine, even during a restore from a backup. Hence a loss, damage, or theft of your machine means the loss of all passwords saved by Safari.
I posted about it here recently: https://news.ycombinator.com/item?id=24626562
I switched to Firefox for this reason. I can't afford to lose all my passwords.
