This is a solution, not a question. Each time an email is Forwarded, Thunderbird shows the email inserted into tables and you see the table boundaries. At the top of the email message (body) you see the "FWD' information. When sending a FWD email, these table boundaries are invisible in the sent email. If this is acceptable, then do not worry about it. ===Removing the "Forwarded Message" part=== What if you wanted to remove the "Forwarded Message" information table at the top of the message (body)? Pressing the delete button does not work, backspacing does not work. Removing content only collapses the table, yet you cannot delete it or cut it or remove it. Sending the email like this still shows a space at the top of the message where the table was, even when the text inside the table was removed. Here is a resolution: (left | right Click refers to Windows) # Click Forward on the email you want to forward, # At the top part of the message where the "Forwarded Message" information shows, left click anywhere inside the text for the "Forwarded Message" information. Table boundaries will appear. # Inside the table box, you will see " <O> " with an "X" inside the circle. When you hover your cursor over the "X" it shows an orange color background inside the circle. # Left Click that "X". # Table content shifts, find the "X" in the circle again, it should at the top of the table box. Click the "X" again. # Table disappears. If not, and it only collapses some more, find the "X" again, click it and it disappears. # Now remove the "Forwarded Message" text like any text in the message and the top part of the Forward message is removed. You can insert anything there instead or leave it blank and even delete the extra space. Just take it slow because the email message below can move up fast. Hope that helps :)
