I don't know why my chrome extension icon isn't showing. I saved all the icons into the images folder hence the /images. it is giving me the blue puzzle piece in the middle Is there something wrong with my code?
This example is working on my browser. I don't know why your manifest json starts with [![. Maybe this is the problem. I'm not sure. Can you edit this example according to your json file?
{
"manifest_version": 2,
"name": "Test",
"description": "Test",
"version": "1.0",
"browser_action": {
"default_icon": {
"16": "images/icon16.png",

"128": "images/icon128.png"
},
"default_popup": "popup.html"
},
"permissions": [
"activeTab"
]
}
Try copy-pasting this into your manifest.json file. You have loads of artefacts that might cause issues, I also removed the default_icons key which isn't necessary in my opinion. Also removed the backslash / before the image folder-paths.

I had the same issues. I opened the png file(s) with paint and resaved them and it worked. So please verify your png files.

Hi I'm creating my first chrome extension here is my minifest file
{
"name": "Get pages source",
"version": "1.0",
"manifest_version": 2,
"description": "Get pages source from a popup",
"browser_action": {
"default_icon": {
"16": "images/get_started16.png",
"32": "images/get_started32.png",
"48": "images/get_started48.png",
"128": "images/get_started128.png"
},
"default_popup": "popup.html"
},
"icons": {
"16": "images/get_started16.png",
"32": "images/get_started32.png",
"48": "images/get_started48.png",
"128": "images/get_started128.png"
},
"permissions": ["tabs", "<all_urls>"]
}
I want to disable the extension for all urls other than few lets say I just want to enable my extension only for yahoo.com and stackoverflow.com what I need to do.
You should use matches in your manifest.
https://developer.chrome.com/extensions/content_scripts#declaratively
For example:
{
"name": "Get pages source",
"version": "1.0",
"manifest_version": 2,
"description": "Get pages source from a popup",
"browser_action": {
"default_icon": {
"16": "images/get_started16.png",
"32": "images/get_started32.png",
"48": "images/get_started48.png",
"128": "images/get_started128.png"
},
"default_popup": "popup.html"
},
"icons": {
"16": "images/get_started16.png",
"32": "images/get_started32.png",
"48": "images/get_started48.png",
"128": "images/get_started128.png"
},
"content_scripts": [
{
"matches": ["http://*.yahoo.com*", "http://*.stackoverflow.com*"]
}
],
"permissions": ["tabs", "<all_urls>"]
}
Btw. avoid all_urls permission if don't need it.
I've created a chrome-extension Reddit hide username. This extension hides your Reddit username when the button in popup.html is clicked.
I want to update it wherein if I visit Reddit, my extension will auto trigger and automatically do its job. How can I do that? Below here is my manifest.json and here's my Github repository
{
"name": "Reddit Hide Username",
"version": "1.0",
"description": "Hide your username in new Reddit UI!",
"permissions": [
"activeTab",
"declarativeContent",
"storage"
],
"options_page": "options.html",
"background": {
"scripts": [
"background.js"
],
"persistent": false
},
"page_action": {
"default_popup": "popup.html",
"default_icon": {
"16": "images/icon16.png",
"32": "images/icon32.png",
"48": "images/icon48.png",
"128": "images/icon128.png"
}
},
"icons": {
"16": "images/icon16.png",
"32": "images/icon32.png",
"48": "images/icon48.png",
"128": "images/icon128.png"
},
"manifest_version": 2
}
I have created a new chrome extension and installed it in developers mode.It is working fine in my laptop. But in some other laptops, the options button is disabled. Please help.
I am unable to share the full code but this is how the manifest.json file looks like:
{
"name": "Asana Actual vs Estimation",
"version": "0.0.1",
"manifest_version": 2,
"description": "Add tags to task if the actual hours exceeds the estimated value",
"icons": {
"16": "icons/icon16.png",
"48": "icons/icon48.png",
"128": "icons/icon128.png"
},
"default_locale": "en",
"content_scripts": [{
"matches": ["<all_urls>"],
"all_frames": true,
"js": ["js/jquery/jquery.js","js/content.js"],
"css": ["css/styles.css"]
}],
"options_page":"options.html",
"permissions": [
"activeTab",
"<all_urls>",
"storage"
],
"content_security_policy": "script-src 'self' https://www.gstatic.com/; object-src 'self'",
"browser_action": {
"default_icon": "icons/icon16.png"
}
}
Thank you!
Its working. This line was not there
"options_page":"options.html"
in manifest.json. Adding that line solved the problem.
How to change Chrome Extension icon in this page?
Here's my manifest code :
{
"manifest_version": 2,
"name": "Demo",
"description": "This is demo.",
"version": "1.0",
"browser_action": {
"default_icon": "icon128.png",
"icons": {
"16": "icon16.png",
"48": "icon48.png",
"128": "icon128.png"
},
"default_popup": "popup.html"
},
"permissions": [
"activeTab",
"storage"
]
}
The icon on toolbar is changed, but not on the chrome://extension page.
Set "icons" key in manifest.json.
The browser_action.icons key is what gets displayed in the toolbar (and will probably only use 16, 24, and 32 sized images, see browserAction).
The one displayed in chrome://extensions is a top level icons key. In the manifest documentation, look for the 6th entry, so that your manifest has an top-level entry, like:
{
"icons": {
"16": "icon16.png",
"48": "icon48.png",
"128": "icon128.png"
}
}
It should be:
{
"manifest_version": 2,
"name": "Demo",
"description": "This is demo.",
"version": "1.0",
"icons": {
"16": "icon16.png",
"48": "icon48.png",
"128": "icon128.png"
},
"browser_action": {
"default_popup": "popup.html"
},
"permissions": ["activeTab", "storage"]
}
See: Chrome Extension Manifest Docs
I'm sure that it is I tried with/without BOM and I still get this error :
{
"manifest_version": 2,
"default_locale": "en",
"name": "__MSG_ext_name__",
"description": "__MSG_ext_description__",
"version": "1.6.0",
"icons": {
"16": "icon_16.png",
"48": "icon_48.png",
"128": "icon_128.png"
},
"browser_action": {
"default_icon": "icon_19.png",
"default_popup": "popup.html"
},
"background": {
"page": "background.html"
},
"options_page": "options.html",
"permissions": [
"tabs"
],
"content_scripts": [
{
"matches": [
"http://*/*",
"https://*/*"
],
"js": [
"scripts/content.js"
],
"run_at": "document_start",
"all_frames": true
}
]
}
I used a program to mass convert all my files in UTF-8, now it works, I think as 方 觉 said, the problem was coming from another file than the manifest.
