What the store shows

The store shows none of its badges on this listing. Most listings carry none.

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

The store lists no publisher name. This listing has been in the store since 2025-01-13 and was last updated on 2025-02-17.

Similar extensions that ask for less
