I am trying to make a chrome extension that alerts you in the tab that you are currently moving or highlighting. I have tried reading the chrome migrating to V.3 documentation and have come up with the following code, however, the alerts never appear. Does anybody know what I need to change or add?
My ‘manifest.json’ file:
{
"manifest_version": 3,
"name": "Alert",
"version": "0.1",
"description": "alerts you when doing tab functions",
"permissions": ["tabs", "activeTab"],
"host_permissions": ["<all_urls>"],
"background": {
"service_worker": "background.js"
}
}
My ‘background.js’ file:
chrome.tabs.onMoved.addListener(function () {
alert("You moved this tab");
});
chrome.tabs.onHighlighted.addListener(function () {
alert("You highlighted this tab");
});
My working directory:
.
├── background.js
├── manifest.json
I figured it out. Alert is not defined in javascript. Also, I was looking in the wrong place for the alert messages. I needed to look at the service worker link in my unpacked extension page.
