    Did your Thunderbird download a duplicate copy of your emails?

    • Maybe your email service provider had to restore your mailbox?
    • Maybe your ISP did a server migration?
    • Maybe a web site went crazy and sent you lots of emails?
    This add-on does a great job of removing the duplicate emails from inbox and folders:

    After downloading the install file:

    Mozilla Thunderbird Tools Addons.JPG Mozilla Thunderbird install addon from file.JPG

    Go to Tools -> Addons and then use the Gear icon to select Install add-on from File.
