clipboard

The WebExtension clipboard API (which is different from the standard Clipboard API) enables an extension to copy items to the system clipboard. Currently the WebExtension clipboard API only supports copying images, but it's intended to support copying text and HTML in the future.

The WebExtension clipboard API exists primarily because the standard Clipboard API doesn't support writing images to the clipboard. The WebExtension clipboard API may be deprecated once the standard Clipboard API's support for non-text clipboard contents has entered general use.

Reading from the clipboard is not supported by this API, because the clipboard can already be read using the standard web platform APIs. See Interacting with the clipboard.

This API is based on Chrome's clipboard API, but that API is only available for Chrome apps, not extensions.

To use this API you need the "clipboardWrite" extension permission.
