This is the second such email I have received recently. Seems legit but I don't recognize the domain in the link to sign, and it seems like the people who make Firefox would know that the people who use Firefox would be hesitant to click. IDGI. Anyone else getting these?

Edit 2024-04-10: Got a new email today and it appears all the links now go to links dot mozilla dot org. I won't flatter myself that this post had anything to do with that, but maybe the same thought occurred to someone at Mozilla. Nice. ✌️
