A prior review: "This extension will have full, unrestricted access to Thunderbird, and your computer. Extensions requesting this permission might: Read, modify and execute any file on your computer." Very dubious. I won't install it until this is fixed."

This review is for a previous version of the add-on (2.1.1).

I think many other add-ons are the same.
Add-ons published on addons.thunderbird.net (ATN) have passed human review.
In addition, the source code of this add-on is open, and anyone can check it.

QUESTION: This may be common practice, but why is it necessary in this case to access any and every file on a user's computer??

Good question.

I found a blog that explains it clearly.

This add-on also uses WebExtension Experiments and will be notified of Case 2 full access requests.

This add-on does not do or need full access. But it uses a conventional mechanism that allows full access. And such add-ons always generate such warnings.
