How I can look for "Sender" header value easily?
I'm talking about "Sender" header and not "From" header!!! https://tools.ietf.org/html/rfc4021#page-7 The only way i found is to look for the source message, The best thing is to see it in the header of the message and/or in the grid of the messages.

Try the Show Address Only add-on. https://support.mozilla.org/en-US/kb/installing-addon-thunderbird
This shows only the "From" header, I need to look for the "Sender" header...
Seems not to be visible through addons! https://bugzilla.mozilla.org/show_bug.cgi?id=494100
Header Field Sender: https://tools.ietf.org/html/rfc4021#page-7 Header field Return-Path: https://bugzilla.mozilla.org/show_bug.cgi?id=494100
Looks like two completely different headers to me. I do wonder if the sender: header is actually commonly included. For instance Yahoo use X-Sender: and they are about the only one in my morning mail that had a sender anything in the header.
I am receiving emails from Outlook Web Access with the "sender:" header and with this header that is different by the "from:" header. It happens when "Antony" sends to "Betty" an email generated by Outlook Calendar (with a "Content-Type: text/calendar;" attachment, but I don't know if this is important) and Betty reply this email to "Charlie". "Charlie" is receiving the email with "from: Antony" and "sender:"Betty" headers. Outlook Web Access shows the email with the string: "Betty on behalf of Antony" in the from position. But with Thunderbird the receiver "Charlie" can see only "Antony" as sender ("from:") and has no information that was "Betty" to send it to him (that is only in the "sender:" header)!
have you tried View menu > headers>all?
Yes, and the "sender:" field is not showed. I can see it only looking for the entire source of the message.
