About this Add-on
This add-on lets you search messages in one or several folders to locate duplicates: Messages which are identical - according to some comparison criteria you chose.
- Wide choice of comparison criteria (subject, author, send time, CC list, flags, etc).
- Review dialog for double-checking which duplicates to delete and which to keep.
- Relatively fast; should easily be able to handle 100K emails and more
- Supports comparison of message bodies as a comparison criteria (but this slows thing down of course).
- Good performance on local folders with large number of messages; reasonable performance with IMAP and RSS accounts.
- Spiffy toolbar button+menu for quick access.
- Free (GPL/LGPL/MPL license)
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.
This version supports v115, except for missing the toolbar menubutton. You will need to use the Tools menu, or the context menu on the folders you've selected, to start a duplicate message search. The comparison criteria can be configured only from the extension's options dialog in "Tools | Add-ons & Themes".
Q: Why are you releasing a beta version?
A: A proper version would require the toolbar button to work, but it's currently broken. Otherwise this would a non-beta release.
Q: Why is the menubutton gone?
A: In the course of the transition to v115, the Thunderbird developers removed the application toolbar in favor of a new "unified toolbar". Unfortunately, they did not document how regular chrome, like this extension, one can add new elements to that toolbar; and it's rather tricky, because its contents deleted and re-generated frequently, so that "just" straightforward adding the button doesn't work.
Other than the compatibility change, additional improvements in this version are:
* Now setting the completion percentage indicators or the "meteros" effect in the status bar during different stages of processing, indicating progress.
* More consistent reporting of what's occurring right now in the status bar, including clearing it when the search is done.
