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?

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.
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",

"128": "images/icon128.png"
}
},
"icons": {
"16": "images/icon16.png",

I have a Chrome Extension project, the structure looks like this:
project/
dist/
index.html
manifest.json
When I go More Tools -> Extensions -> Load Unpacked Extensions
I choose the root of the project, and it works! But I can't figure out how it knows to load dist/index.html? The manifest.json file doesn't say anything about dist/index.html, so how does Chrome know how to load the extension?
I built this extension a few months ago, and now I can't figure out how it works lol.
the manifest.json file looks like this verbatim:
{
"manifest_version": 2,

I'm sure that it is I tried with/without BOM and I still get this error :

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.
