Rated 4 out of 5 stars

This used to work until a few weeks ago, now I get the following error in the developer console:

NS_ERROR_XPC_CANT_MODIFY_PROP_ON_WN: Cannot modify properties of a WrappedNative

Apparently, the plug-in only worked up through Thunderbird v78 or so, and a fix is expected this winter.

The need to hit Enter when adding email address place holder is not obvious, nor is the reason why sometimes Nunkucks works and sometimes Legacy parsing works for a message. But overall, when it's working, it's pretty good.

This review is for a previous version of the add-on (2.3).
