Incoming msges from known and trusted correspondent often replicates itself from several times up to 823. Drafts I create do likewise. I notice someone else has reported a similar experience: interesting there are 2 replies: however these cannot be read so other than knowing others are experiencing the same problem as I am, the Mozilla system does not help on that screen. I am disappointed that on previous occasion when I have raised this issue, there has been no useful response. The clickable icons with suggested problems and solutions do not address this issue. I look forward to meaningful advice.
