Email address not showing inside email

[Krumplestiltskin]

In emails where there are previous replied-to emails below, the headers for the previous emails do not contain the email address, only the display name. How can I get these headers to show the email address instead of the display name? (Please note, I am not referring to the message list or thread pane, but rather to the actual email content). Thanks for any help!

Try menu path Thunderbird → Preferences->Display->Advanced->uncheck "Show only display name for people in my address book."

I already tried that solution, but that did not work. Please see an example below:


<---------
This is a reply to your test email. <---- this is the email reply.
--------------------------------------------------------
*From:* Testy Mctesterson <----- I want this to be a clickable link or an email address, but it just shows the display name.

This is a test email. <----- this is the original email.

I am not sure if there is a OOTB option for this. But, I am using this extension. Try this and let us know if this is what you are looking for. Download link is at the bottom of the page.
