Review for Folder Account by Comunica2
Rated 4 out of 5 stars
Seems precisely what I was looking for but asking "... full, unrestricted access to Thunderbird, and your computer" is a bit too much risk for my taste. I give the average 4 stars evaluation only for the idea.
I would like to see the TB API be more specific and or better organized to allow the functionality of this plugin without full access. I wait with using this add-on until then. I would like to know if there is a way to influence this, without being a TB developer.
TB 91.4.1 under Linux
Update: Since version 12.1 this isn't an issue anymore.
Thank you for your kind review! Thunderbird's still evolving modern WebExtension API should eventually provide all needed functionality for this and many other add-ons. In the meantime one has to trust the thorough review each legacy add-on has to pass.
