Duplicate Email Remover
Finds and removes duplicate emails across your Thunderbird folders. It uses the Message-ID header for reliable matching, so a duplicate has to genuinely be a duplicate — no false positives from similar subjects, dates, or senders. For the rare message with no Message-ID, it falls back to subject + sender + size + timestamp-to-the-minute.
Quick start
Click the toolbar icon (envelope-pair) to open the popup.
Expand "Folders to scan" and check the folders you want scanned. Your selections persist across sessions.
Choose which copy to keep (oldest or newest) and one of three actions: move duplicates to Trash, delete permanently, or move to a folder of your choice.
Click Scan for Duplicates. Each duplicate group displays the copy that will be kept (green KEEP badge) and each copy that will be removed (red DELETE badge). Click any row to preview the message before deciding.
Uncheck any group you don't want touched, tick the confirmation box, and click the action button.
Extension-wide preferences (default keep-strategy, default action, which folder types to skip, silent mode, diagnostics) live on the Options page: Add-ons and Themes → Duplicate Email Remover → Options.
Entry points
Toolbar button (envelope-pair icon) in Thunderbird's main mail window — opens the popup with all scan controls and results. This is the only entry point during normal use.
Options page — Add-ons and Themes → Duplicate Email Remover → Options. Sets defaults for future scans (which copy to keep, which action to take, which folder types to skip, diagnostics on/off).
Options page
Automatically skip Drafts, Sent, Templates, Outbox, and Archives — each an independent checkbox. Defaults: Drafts, Sent, Templates, Outbox on; Archives off (so Gmail "All Mail" gets scanned).
Skip messages already marked deleted on IMAP servers (on by default).
Default keep-strategy and default action for new scans.
Silent mode to skip the confirmation checkbox (off by default, recommended off).
Update log
Version 1.2.0
-Scans survive clicking elsewhere in Thunderbird. Pressing Scan opens a detached window that doesn't close on focus loss; only the scan itself is detached, setup still happens in the toolbar popup.
-Cancel button next to the progress bar interrupts a scan (between folders — mid-folder cancel isn't possible through the WebExtension API).
-Account filter above the folder tree limits the visible list to one account at a time; Select all / Select none respect the current filter so bulk-toggle only touches visible folders.
-Cascade selection toggle in the folder tree header: on by default (parent → subfolders), turn off to toggle only the folder clicked.
