Sender and Recipient columns vanished

[ghuareg]

I don't know why, and can't see how to get them visible again. Can someone tell me how, please?

[DanRaisch]

At the right end of the column header bar is a small box. Click on that to display the list of available columns. Make sure that "Correspondents" is selected to display those columns.

Sorry Dan, but I can't see that anywhere, or associated drop-downs. See here.

[DanRaisch]

OK that's because you are referring to the Sender and Recipient header values in the message itself, not in the message list pane that I thought you were speaking of.

Are those values visible if you press Ctrl+U to display the message source?

An email from Moz Forum seems to show sender:

If I view outgoing message source, there is a "To" line of the addressee's email address.

Next step, please?

Does the same thing occur if you launch the application in Mozilla Safe Mode? http://kb.mozillazine.org/Safe_mode

[ghuareg]

Yes, but something happened to make me update TB. I won't go in to detail. All is now OK.

[DanRaisch]

Glad to hear that.
