hi i have been having a problem with creating a chrome extension the extensions js script dosent run unless i click on the icon and let the extension html stay there if i close the little icons menu it stop the javascript file too
is there a way to let the script run when the tab opens and finish the timeout?
and would it be better to use the chrome.alarm then setTimeout?
here is the manifest
{
"manifest_version": 2,
"name": "test",
"description": "",
"version": "1.0",
"browser_action": {
"default_icon": "icon.png",
"default_popup": "index.html"
},
"content_scripts": [
{
"matches": ["<all_urls>"],
"css": ["style.css"],
"js": ["main.js"]
}
],
"permissions": [
"activeTab",
"storage",
"tabs"
]
}
here is the main.js
check();
function check(){
setTimeout(function(){ alert('hi'); }, 3000);
}
chrome.tabs.onCreated.addListener(function(tab){
alert('hi');
})
the function and chrome.tabs.onCreated only fires when i click the icon and open the popup html

I'm trying to intercept youtube requests response from a devtool panel and send it to the content or background script of a Chrome extension. but I can't get it to work.
There is loads of exemple online but most of them use Manifest V2 and I really want to make it work on V3.
I don't know which method to use for sending messages to the content or background script from the panel.js, nor do I know how to listen for incoming messages from the panel in those scripts.
And I don't know if I need to add more permissions in my manifest for this to work :
{
"manifest_version": 3,
"name": "Already Seen",
"version": "1",
"content_scripts": [
{
"matches": ["<all_urls>"],
"js": ["jquery-3.6.0.min.js", "content.js"],
"css": ["avatar.css"]
}
],
"devtools_page" : "devtools.html",
"action": {
"default_icon": "icon.png"
},
"background": {
"service_worker": "background.js"
},
"permissions": ["identity", "storage", "tabs", "webRequest"],
"host_permissions": ["https://www.youtube.com/", "https://youtube.com/"],
"externally_connectable": {
"matches": ["https://youtube.com/*"]
},
"oauth2": {
"client_id": "***************",
"scopes": [
"https://www.googleapis.com/auth/userinfo.email",
"https://www.googleapis.com/auth/userinfo.profile"
]
}
}
devtools.html
<script src="devtools.js"></script>
devtools.js
chrome.devtools.panels.create("Already Seen", "icon.png", 'panel.html');
panel.html
<html>
<body>
<script src="panel.js"></script>
</body>
</html>
panel.js
chrome.devtools.network.onRequestFinished.addListener((request) => {
request.getContent((body) => {
if (!request.request || !request.request.url) return;
// I NEED TO SEND THE MESSAGE HERE TO BACKGROUND.JS OR CONTENT.JS
});
});
I found another way of doing this by using the chrome.debbuger in the background script but it shows "... started debugging this browser" on top of every pages.
I'd like to develop a chrome extension and add my custom CSS and JS;
I have these Two files:
manifest.json
{
"name": "Block request",
"version": "1.0",
"manifest_version": 2,
"content_scripts": [{
"matches": ["<all_urls>"],
"js": ["content_script.js"]
}],
"permissions": [
"webRequest",
"webRequestBlocking",
"<all_urls>"
]
}
content_script.js
if (window.location.hostname = "w3schools.com") {
alert("Hello");
console.log("Hi console");
}
I added this extension to the Chrome, but when I refresh every page I got alert message;
How can I solve this issue?
Is my coding correct?
I am building a Chrome extension that injects some HTML and JS when the user clicks the extension icon. So, when the icon is clicked, it is registered in the bg script, and the content script is notified about this like so:
Background script
chrome.browserAction.onClicked.addListener(iconClicked)
function iconClicked(tab) {
var visitors = window.AllVisitors.get(tab.id),
data = {
message: 'toggleMenu',
user: window.user
};
chrome.tabs.sendMessage(tab.id, data);
}
Now, to the problem: In my manifest file, I have also added a custom page for the chrome://newtab page. When the extension icon is clicked while visiting this custom newtab page, the content script does not receive any message what so ever. The default newtab page does actually receive the message as well as any other webpage.
I am thinking that maybe it has something to do with externally_connectable, but adding this does not help:
"externally_connectable": {
"matches": ["chrome://newtab/"],
}
Does anybody know why my custom newtab page does not receive any messages from the background script? Any help is very appreciated!
Manifest file:
{
"manifest_version": 2,
"name": "Orbit",

Content scripts aren't injected on chrome-extension:// pages.
Simply add the script manually in your newtab.html:
<html>
<head>
<script src="your-content-script.js"></script>
</head>
As you can see, I have a problem with onclick event in chrome extension and I need your help.
$(function jony() {
jQuery.each( jQuery('img'), function() {
jQuery(this).attr('src', 'urlimage');
});
});
chrome.browserAction.onClicked.addListener(function(tab) {
jony();
});
Manifest:
{
"manifest_version": 2,
"name": "Jonyzátor",
"description": "Change images on page to JoNy!",
"version": "1.0",
"browser_action": {
"default_icon": "icon.png",
"default_title": "Klikni na mě!"
},
"permissions": [
"activeTab",
"https://ajax.googleapis.com/"
],
"content_scripts": [ {
"js": [ "jquery.js", "jonyza.js"],
"matches": [ "http://*/*", "https://*/*"]
}]
}
The scope in which jony is defined is limited to $(); outside it's simply undefined.
function jony() {
jQuery.each( jQuery('img'), function() {
jQuery(this).attr('src', 'urlimage');
}
$(jony); // Will execute on page load
// and you can still use it here
I'm not sure it was the logic you intended - do you want it to run both at page load AND when you click?
You can't use browserAction API in content scripts. The proper place for it would be a background (or event) script, and then you can message your content script to do something.
I want to be able to click the HTML div button and relocate the current tab.
redirect.js
chrome.browserAction.onClicked.addListener(function(tab) {
chrome.tabs.update(tab.id, {
url: "http://www.roblox.com/"
});
});
popup.html
<html>
<script src="redirect.js"></script>
</html>
manifest.json
{
"name": "z",
"version": "0.1",
"description": "z",
"background": {
"page":"popup.html"
},
"manifest_version": 2,
"content_scripts": [
{
"matches": ["http://*/*", "https://*/*"],
"js": ["redirect.js"]
}
],
"permissions": [
"tabs",
"bookmarks",
"<all_urls>",
"unlimitedStorage"
]
}
Those are my current scripts, it doesn't let me use onclick when I add a div button, I need that help mainly.
1: you did not specify the browserAction in the manifest.json. If you want to use chrome.browserAction.onClicked, you have to specify a browser action. add an extension icon.
2: you do not need content script
3: if you only want a single redirect function, you do not need to request bookmarks and all urls and storage permissions.
so here is your manifest.json should be :
{
"name": "z",
"version": "0.1",
"description": "z",
"background": {
"page":"popup.html"
},
"manifest_version": 2,
"permissions": [
"tabs"
],
"browser_action": {
"default_icon": {
"19": "icon.png" //you have to put an image icon.png in to the folder.
},
"default_title": "Redirect" //optional
}
}
Then it will works.
plus, do not name your background file as "popup.html", popup usually used as a popup window.
you can also download the extension here, only this script will redirect to google after click. you can modify it yourself.
