Hello. Is there a way for a fellow gmail user to tell if another recipient who also uses gmail ,if a message they have sent has been opened,and/or forwarded to another gmail user? Thankyou.

Hi
This does not sound like an issue with Firefox but is something that the Gmail support team should be able to help you with.
A lot of email senders (mostly bulk email senders) use "beacon" images to detect that a message was viewed. This is why you can usually choose not to load images in a message until you first confirm that you want to do that.
