What steps are you taking? For example, if you rightclick and select 'edit as a new message', that warning appears. But it should not if you just click 'reply'

When I open my email in Thunderbird, the Reply/Forward commands are not shown in the Toolbar and the reply address is directed to me, not the sender. It is just lately the emails have been doing this and I don't know how to fix it back to the way it was.

I haven't received any solutions to this problem ?

Please send a screenshot of Thunderbird with the problem highlighted.

I think your Inbox is acting like a Drafts folder:

It seems I cannot find a solution to this problem and I have run out of options. can Mozzila possibly phone and offer a solution? I do not know how to take a screenshot of the offending emails because every email shows the problem. I receive the emails with my email address in the senders line. The email doesn't come as it used to with reply/forward commands in the Tool Bar line .To reply to an email, I have to remove my address and type in the proper address then click on File ,scroll down and click on send now . Some of the suggestions show commands I don't see on my screen so I am stopped in doing what they suggest.
