permissions contain items from a list of known strings (such as "geolocation")wW0无知
optional_permissions are like regular permissions, but are granted by the extension's user at runtime, rather than in advancewW0无知
host_permissions contain one or more match patterns that give access to one or more hostswW0无知

Permissions help to limit damage if your extension is compromised by malware. Some permissions are displayed to users for their consent before installation or at runtime as needed, as detailed in Permission Warnings.wW0无知

You should use optional permissions wherever the functionality of your extension permits, to provide users with informed control over access to resources and data. See the platform vision to better understand this recommendation.wW0无知

If an API requires you to declare a permission in the manifest, then its documentation tells you how to do so. For example, the Storage page shows you how to declare the "storage" permission.wW0无知

Here's an example of the permissions part of a manifest file:wW0无知

"permissions": [  "tabs",  "bookmarks",  "unlimitedStorage"],"optional_permissions": [  "unlimitedStorage"],"host_permissions": [  "http://www.blogger.com/",  "http://*.google.com/"],
