Hi umk75,

Its a temporary solution:

Goto Settings - Then under General Settings scroll down to Config Editor - Then copy mail.compose.attach.dir and paste to search bar - Delete the setting - .

Attachment button start working. If is it happen again then repeat above steps.

It was a bug in desktop, and it is fixed with the v158.0 release. If your TB hasn't updated yet, go to TB menu > Help > About Thunderbird.

Thank you very much!
