it does not work any more?

[traut21]

I have some mails which are

• forwarded through a mailing list,
• receive a subject prefix
• receive a mailing list footer
• are picked up from different servers

So my Remove Duplicates setup is to use matching

• author
• message id
• send time

However, duplicates are neither recognized nor removed. It had been working with a much older thunderbird version. But since I moved to a new MacBook Pro with newer MacOS and newer TB 115.6.1, it does nothing now.

Example:
Message-ID: [email protected]
Date: Tue, 16 Jan 2024 18:32:35 +0100
MIME-Version: 1.0
User-Agent: Mozilla Thunderbird
To: ***@googlegroups.com

I have tried to close/open Thunderbird and to repair the folder.

• Do you find dupes if you remove all criteria?
• Do you get any errors in the Error Console that mention "removedupes"?

Thanks for having a look into it.

The Error Log says:

NS_ERROR_NOT_INITIALIZED: mailWindow.js:515
TypeError: tab.chromeBrowser.contentWindow is null. mailTabs.js:177:13
Error: Invalid window ID: 1125 undefined
