And I mean, there's still time now. Switching browsers isn't that bad. Export+import some bookmarks and adjust some settings, good to go.
I think FF has been a good option for a while. But the second best time is now. I can totally get it if people didn't want to switch until they had more of a concrete problem.
Understandable, I'm really looking forward to FF getting tab groups too. I don't know why such a nice feature was left unimplemented for so long. π«€
