Is this in the subject list in the templates folder, or when you open the template. If in the list, it sounds like the column is not wide enough for the subject. Can you read "subject in the list heading or is it blank?

Try dragging the column separator on the right of the subject in the list to the right.

Hello,

Thank you for your reply.

The issue happens in both case. In the templates list, the "Subject" column is actually the widest and has enough space to display the title entirely. I tried to resize it anyway but without success. Plus, when I open the template (to edit it or write a mail based on it), the Subject field do display "..." instead of the title I used when creating the template.

I attached a screenshot to show the templates folder and the template edition window in case it's useful.

I did locate a bug report: https://bugzilla.mozilla.org/show_bug.cgi?id=1684850

Do you use eg: OpenPGP for sending encrypted messages If yes: then perhaps the other bug report https://bugzilla.mozilla.org/show_bug.cgi?id=1666005

In the 'Drafts' folder is the 'Message Pane' enabled ?

Enable the 'Message Pane' if not enabled and select saved draft email in list so it is displayed in Message Pane, then click on 'Edit'. Does this work as a workaround ?

Hello,

Looks like OpenPGP was the one messing around! I edited my template, set my title, and then I went under "Security > OpenPGP" and I disabled "Subject encryption". When I saved the template, the title was this time persisted properly in my Templates folder.

Thank you for your help :)
