Hello. Through our research, we are seeing that the Firefox app isn't offering a printer friendly version of the email. Please try to print from a different browser to see if you get the whole email printed. Please let us know what happens. If that doesn't work, you can reach out to Firefox for assistance with the app, as this is outside our scope of support. Perhaps another Forums member will have some other input. You can try to save the email in a PDF document or copying and pasting the body of the email and printing it. You can also subscribe to Cox Complete Care if you are not already subscribed, and reached out to them and they can assist you.
