The developer responded quickly explaining the reasoning behind the permissions requested with detail.
Thanks for informing me about how these addons work, and for your contribution to the platform and providing open source code to verify your authenticity.
The software works perfectly and helps me with my work as well.
ご迷惑をお掛けしてすみませんでした。 どうもありがとうございます!!
Have full, unrestricted access to thunderbird, and your computer???
I've never even seen an addon ask for such unfettered access.
Why in the world would your software need that?
No one should ever allow anyone those kinds of privileges. Do not under any circumstances install an addon that asks for that.
Please fix.
A blog below 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.
You say you have never seen such add-ons, but there are still many such add-ons.
This add-on is also open source code. If in doubt, look into it.
If you don't want to do that either, you can of course choose not to use it.
To create your own collections, you must have a Mozilla Add-ons account.
