Derived from the manifest by Chrome's documented rules; the dialog's exact wording depends on your Chrome version and language. Chrome asks again if an update requests more.
What it can reach

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
Mekiah Smith. This listing has been in the store since 2015-05-31 and was last updated on 2015-05-31.
Similar extensions that ask for less
