I'm all in on FF on desktop.

The only thing stopping on mobile for last 4-5 years is Translations. Project Bergamot is incredibly successful, thanks again to Mozilla for investing in this! Open Translation is such an important thing, it's a game changer.

It went from beta to addon to bring built into desktop Firefox since the latest release. No words can express the amount of gratitude for this. Now, just waiting for it to be enabled in android builds.

Edit: Another not so highlighted feature of Firefox is: Mac always shows Chrome as "significantly consuming energy". But never for Firefox. I don't know what magic they did here.

Edit 2: Don't get me started on the benefits of containers, profiles and temporary containers as a default.
