It's an improved version of Header Tools Lite by Paolo Kaosmos, it has been renamed to avoid confusion.
Notes for version 4.0 for Thunderbird 115 and beyond:
Version 4.0 of this add-on only worked when messages were visible in the Message Pane, this was fixed in version 4.10 for Thunderbird 128.
The Message Pane context submenu was removed for messages opened in a separate tab or window.
The Menu Bar Message menu submenu was removed.
A save & restart button was added to the options page, right-click context menus were fixed throughout the add-on, UTF-8 encoded Reply-To headers are decoded properly.
The editing features (changing the headers only or the entire source of a message) are accessible from the context menus in the message list and the message pane (not for messages opened in a separate tab or window).
The edit source function should be used with caution, because an error could cause problems in displaying all messages in a folder. Moreover, it could work not properly with some characters and some encodings.
Options for the extension:
- Put the original message to the Trash (default = true): the changes are made by creating a copy of the original message. This option controls whether the original message goes to the Trash folder, or is deleted.
- Forcing changes with IMAP accounts (default = true): some IMAP servers, such as Gmail, do not accept changes if some basic headers (date, sender, the message id, object) are not modified . With this option enabled, the changes are forced by changing the date of the message by 1 second.
- Add the header X-HeaderToolsImproved (default = false): by enabling this option, every change (edit) adds a header that describes the type of change and its time and date.
- Set the maximum number of characters initially displayed when editing the full source (default = 150000).
- The default keyboard shortcuts have not been set, you can set these yourself.
