Used Firefox to log into my Yahoo email account. Had email notifying me of a purchase ready for pickup at Home Depot. Tried to print the email using the tap at the top of the email, but Firefox left several pages blank in the Preview. I then opened up Chrome and logged into my Yahoo account, brought up the email, and clicked Print. Google notified me that I had to allow pop-ups to display the full content of the email for printing. Once I did that, I printed the email without difficulty. Firefox needs to be updated to notify users of issues like this. There was nothing on Firefox to indicate what the problem was in printing. Thank you.
