Do Chrome Apps have the same permissions available to them as Extensions?

Question

This page:https://developer.chrome.com/extensions/browsingData

softly suggests no with the wording of things like: You must declare the "browsingData" permission in the extension manifest to use this API.

presumably there is a difference between the app and extension manifest?

Answer 1

No. Here is a list of permissions an App can declare and here is a list of permissions an extension can declare. There is a lot of overlap but app permissions tend towards self contained functionality while extensions are geared more towards interacting with other tabs and websites you visit.
