Send & Archive (Thunderbird Add-on)

This add-on adds a Send & Archive action to Thunderbird compose windows.

Behavior

• Shows a Send & Archive button in the compose toolbar.
• Adds the shortcut Ctrl+Shift+Enter.
• Works for reply, reply-all, and forward compose windows.
• Archives the original message only after send succeeds.

Disclaimer and support

• This extension was created by me for personal use only.
• It is not officially supported.
• It will only be updated when I personally see a need.
• Everyone is welcome to contribute if they want.

Development notes

• The add-on reads relatedMessageId from compose details.
• It calls compose.sendMessage(...) first.
• Only if sending resolves successfully does it call messages.archive(...).

Releases

• Releases follow semantic versioning (MAJOR.MINOR.PATCH).
• Release commit messages follow semantic-release style (Conventional Commits), for example: chore(release): 1.0.2.

Build/package

Create an installable .xpi automatically:

./scripts/package.sh

This produces a file in dist/ named from the manifest version, for example:

• dist/send-and-archive-1.0.2.xpi

Install in Thunderbird

1. Open Thunderbird.
2. Go to Add-ons and Themes.
3. Click the gear menu and choose Install Add-on From File....
4. Select the generated .xpi file from dist/.
