By implementing userScripts, extension developers can modify how sites look and/or work to better meet user needs.
Implement userScripts in your extension using the following steps:
- Define the script in the extension's manifest using the
"user_scripts"
key. - Register the userScript
- Implement the userScript functions
Let's step through the processes using a small sample web extension that illustrates the process. The example is available in the webextensions-examples repository on GitHub.
