This add-on does not seem to be supported since Thunderbird 73. Users looking for a successor might like to try "Unwrap Signature" <https://addons.thunderbird.net/de/thunderbird/addon/unwrap-signature/>.

I waited so long for this after "Header Tools Lite" gone unsupported. Just right click on a signed message and "disable signature". Separating large attachments is now possible again. Works like a charm. Thanks!
