The attachments may be present or embedded (possibly ContentID cid: links) in a way that is incompatible with Firefox, but will work with an email program or IE.

Thank you very much for taking the time to respond to my baffling dilemma. Unfortunately I have no idea what to do with your advice? Is ContentID cid something that I have control over? I suspect that the answer to my problem is elemental and is something very seldom considered by rocket scientist or other like minded intellectuals. It is a reoccurring problem which suggests that it is a fundamental settings error which should be easily solved. I simply need to know which button to press. It is not my intention to appear flippant but simplicity in any response would be appreciated. ,
