To create your own collections, you must have a Mozilla Add-ons account.
Some add-ons ask for permission to perform certain functions. Since you’re in control of your Thunderbird, the choice to grant or deny these requests is yours.
Please note this add-on uses legacy technology, which gives it access to all browser functions and data without requesting your permission.
