This sample demonstrates using the chrome.userScripts API to inject JavaScript into web pages.

Clicking this extension's action icon opens an options page.

1. Clone this repository.
2. Load this directory in Chrome as an unpacked extension.
3. Click the extension's action icon to open the options page.
4. Once a user script has been configured, visit https://example.com/.

This sample allows you to inject the following:

• Files
• Arbitrary code

The User Scripts API requires users to enabled developer mode. We check for this by attempting to access chrome.userScripts, which throws an error on property access if it is disabled.

When a change is made on the options page, use the chrome.userScripts API to update the user script registration.
