Tb 60.9 incompatible

Which was the prior Thunderbird version? Which AE version?

There are two possibilities. Either, you provide more accurate data, or I can not help you. The "latest" version is not a specific version to deal with.

Because of no further information by the thread starter, I set this Thread to "fixed". On ATN is AttachmentExtractor Continued in version 1.5.3 for Thunderbird 60.* available.
