Chrome extensions are built from several key parts including background scripts, content scripts, UI elements, and options pages.
Start a new Chrome extension project by creating a folder and a `manifest.json` file with the three mandatory fields: name, version, and manifest_version.
Enhance the extension's presentation by adding an `icons` object and a `description` field to the `manifest.json` file.
Implement a `background.js` script that uses the `chrome.webRequest.onBeforeRequest` API to intercept navigation to specific URLs and redirect the user.
Fix errors by adding a `permissions` array to the manifest for APIs like `webRequest` and `webRequestBlocking`, and use the extension management page for debugging.
Create a user interface that appears when the extension icon is clicked by defining a `browser_action` in the manifest and linking it to a popup HTML file.
Use a `popup.js` script to add event listeners to buttons, allowing users to create and cancel alarms with the `chrome.alarms` API.
The background script listens for events using `chrome.alarms.onAlarm` and then creates a persistent desktop alert with `chrome.notifications.create`.
