runtime.PlatformOs
Identifies the browser's operating system.
runtime.PlatformArch
Identifies the browser's processor architecture.
runtime.PlatformInfo
Contains information about the platform the browser is running on.
runtime.RequestUpdateCheckStatus
Result of a call to
runtime.requestUpdateCheck()
.
runtime.OnInstalledReason
The reason that the
runtime.onInstalled
event is being dispatched.
runtime.OnRestartRequiredReason
The reason that the
runtime.onRestartRequired
event is being dispatched.
runtime.lastError
This value is set when an asynchronous function has an error condition that it needs to report to its caller.
runtime.id
The ID of the extension.
runtime.getBackgroundPage()
Retrieves the Window object for the background page running inside the current extension.
runtime.openOptionsPage()

runtime.setUninstallURL()
Sets a URL to be visited when the extension is uninstalled.
runtime.reload()
Reloads the extension.
runtime.requestUpdateCheck()
Checks for updates to this extension.
runtime.connect()
Establishes a connection from a content script to the main extension process, or from one extension to a different extension.
runtime.connectNative()
Connects the extension to a native application on the user's computer.
runtime.sendMessage()
Sends a single message to event listeners within your extension or a different extension. Similar to
runtime.connect
but only sends a single message, with an optional response.
runtime.sendNativeMessage()
Sends a single message from an extension to a native application.
runtime.getPlatformInfo()
Returns information about the current platform.
runtime.getBrowserInfo()
Returns information about the browser in which this extension is installed.
runtime.getPackageDirectoryEntry()
Returns a DirectoryEntry for the package directory.
runtime.onStartup
Fired when a profile that has this extension installed first starts up. This event is not fired when an incognito profile is started.
runtime.onInstalled
Fired when the extension is first installed, when the extension is updated to a new version, and when the browser is updated to a new version.
runtime.onSuspend
Sent to the event page just before the extension is unloaded. This gives the extension an opportunity to do some cleanup.
runtime.onSuspendCanceled
Sent after
runtime.onSuspend
to indicate that the extension won't be unloaded after all.
runtime.onUpdateAvailable
Fired when an update is available, but isn't installed immediately because the extension is currently running.
runtime.onBrowserUpdateAvailable
Fired when an update for the browser is available, but isn't installed immediately because a browser restart is required.
runtime.onConnect
Fired when a connection is made with either an extension process or a content script.
runtime.onConnectExternal
Fired when a connection is made with another extension.
