About this Add-on
The original 'Remove Duplicate Messages' is missing important features, and does not have a free software license. This is a full rewrite, with an GPL-LGPL-MPL license. Performance has been improved and many features and capabilities have been added, including:
- Choice of comparison criteria (subject, author, date, etc).
- Comparison of message bodies.
- Action on multiple folders.
- Review dialog for double-checking which duplicates to delete and which to keep.
- Good performance on local folders with large number of messages; reasonable performance with IMAP and RSS accounts.
- Spiffy toolbar button+menu.
I had tried contacting the author of the original 'Remove Duplicate Messages' several times, without success. I would have liked to join forces and have just one extension, but that doesn't seem to work out.
Also, some locales are incomplete - help with them would be appreciated. Visit the BabelZilla translation website.
* Compatiblity: Thunderbird v59 changed the name of the date formatting service
* Compatiblity: Thunderbird 57 dropped support for what is now a "legacy" version of the generator mechanism, in favor of the ECMAScript ES 6 standardized mechanism for generators; now using that.
* Fix/Compatiblity: Newer versions of Thunderbird don't accept a JS version number in the script type field in XUL files, so -we've dropped them
* Fix: Shortcut key clash with the Lightning (calender) extension
