Is this a question about Thunderbird or about an online email service with Firefox ?

If the question is about Thunderbird then we can move the question thread to Thunderbird Support.

I am female, 83. I have no idea what Thunderbird is. I have Outlook live email and if you look at the attachment I sent, it shows on the top line and "Ad" "remotepc". I cannot block the Ad nor delete it.

I suggest a Firefox extension. It blocked a similar ad I was getting with another email provider.
