About this Add-on
This extension allows the user to change (edit) messages in any folder.
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:
Due to changes in Thunderbird this add-on now only works with messages opened in the Message Pane.
The Message and Message list context menus only appear when a message is visible in the Message Pane.
The Message menu submenu had to be 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.
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.
