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

DupeDrop. This listing has been in the store since 2020-12-31 and was last updated on 2022-09-20.

Similar extensions that ask for less
