Arc is much more than that, though. 1st. Tabs are both tabs and bookmarks. They exist to be more or less persistent (as long as you add them to folders - I get it, it's not everyone's workflow, but for people like me, it's a blessing). 2nd. It has a brilliant tab sync between devices. Something Firefox doesn't do - in fact, only Edge does that. 3rd. Is much lighter on resources on macOS. Some months ago I decided to give a - yet another - try at Firefox on my MacBook and I started not being able to do my full work day job on battery. At first, I didn't understand what was going on and thought it was docker that was killing the battery. Then I went to investigate, and yup, it was Firefox, again, after all these years of telling that now they are good on macOS. No, they aren't, they still use 4x more battery than Edge, or Arc, or Brave... TLDR: Give Arc a try. You might be pleasantly surprised.
