What the store shows

Has it asked for more over time?

This is the question a permission list on its own cannot answer. An extension that shipped narrow and widened later is a different proposition from one that always asked for the same thing.

The permissions this extension requests have not changed since we started watching it.

Who publishes it

DF Dev, who publishes 2 listings we track. This listing has been in the store since 2026-07-22 and was last updated on 2026-07-22.
