does not remove the attachment. 128.2.1.esr 64-bit

This review is for a previous version of the add-on (1.4.3). 

Extract 'Em! does not remove the attachment by default. However, the option is available (Permanently Detach) after the fact. Some users have reported that this feature is not working; I am consulting with the Thunderbird API team regarding the issue.
