Declares which extensions, apps, and web pages can connect to your extension via runtime.connect and runtime.sendMessage.
3 nested properties
Indicates that the extension would like to make use of the TLS channel ID of the web page connecting to it. The web page must also opt to send the TLS channel ID to the extension via setting includeTlsChannelId to true in runtime.connect's connectInfo or runtime.sendMessage's options.
You can use this API to enable users to upload files to your website.
Specify how this extension will behave if allowed to run in incognito mode.
Allows your extension to handle keystrokes, set the composition, and manage the candidate window.
This value can be used to control the unique ID of an extension, app, or theme when it is loaded during development.
One or more mappings from MIME types to the Native Client module that handles each type.
Use the Chrome Identity API to authenticate users: the getAuthToken for users logged into their Google Account and the launchWebAuthFlow for users logged into a non-Google account.

To allow users to customize the behavior of your extension, you may wish to provide an options page. If you do, an Options link will be shown on the extensions management page at chrome://extensions which opens a dialogue containing your options page.
3 nested properties
The path to your options page, relative to your extension's root.
If true, a Chrome user agent stylesheet will be applied to your options page. The default value is false, but we recommend you enable it for a consistent UI with Chrome.
If true, your extension's options page will be opened in a new tab rather than embedded in chrome://extensions. The default is false, and we recommend that you don't change it. This is only useful to delay the inevitable deprecation of the old options UI! It will be removed soon, so try not to use it. It will break.
Technologies required by the app or extension. Hosting sites such as the Chrome Web Store may use this list to dissuade users from installing apps or extensions that will not work on their computer.
2 nested properties
Indicates if an app or extension requires NPAPI to run. This requirement is enabled by default when the manifest includes the 'plugins' field.
1 nested properties
The '3D' requirement denotes GPU hardware acceleration.
1 nested properties

Defines an collection of app or extension pages that are to be served in a sandboxed unique origin, and optionally a Content Security Policy to use with them.
2 nested properties
This introduces some fairly strict policies that will make extensions more secure by default, and provides you with the ability to create and enforce rules governing the types of content that can be loaded and executed by your extensions and applications.
The short name is typically used where there is insufficient space to display the full name.

1 nested properties

An array of resources to be exposed. Resources are specified as strings and may contain * for wildcard matches. For example, "/images/" exposes everything in the extension's /images directory recursively while ".png" exposes all PNG files.
A list of URL match patterns specifying which pages can access the resources. Only the origin is used to match URLs; subdomains patterns (*.google.com) and paths are ignored.
A list of extension IDs, specifying which extensions can access the resources.
If true, only allow resources to be accessible through dynamic ID. The dynamic ID is generated per session. It's regenerated on browser restart or extension reload.
