Unable to see icon under chrome://extensions/

[Nathan Pierce]

​Here is my manifest.json:

{

"name": "Vertically Listed Tabs",

"description": "Manage your tabs vertically!",

"version": "0.2.1",

"manifest_version": 3,

"permissions": ["tabs","favicon","storage"],

"action": {

"default_title": "Open the VLT panel window.",

"default_icon": {

"16": "img/favicon-16x16.png",

"32": "img/favicon-32x32.png",

"48": "img/favicon-48x48.png",

"128": "img/favicon-128x128.png"

}

},

"background": {

"service_worker": "background.js",

"type": "module"

},

"options_ui": {

"page": "options/options.html",

"open_in_tab": true

}

}

The files are png and look fine.



Yet, the in the extensions page (and I've tried Removing and re-loading multiple times), I don't see anything but some default gray icon with a V in it.

Hi there,

You must use this in your manifest:

"icons": {

"16": "img/favicon-16x16.png",

"32": "img/favicon-32x32.png",

"48": "img/favicon-48x48.png",

"128": "img/favicon-128x128.png"

},

The "default_icon" is for the icon only in your Chrome toolbar.

Thanks,

Still no change.

{

"name": "Vertically Listed Tabs",

"description": "Manage your tabs vertically!",

"version": "0.2.1",

"manifest_version": 3,

"permissions": ["tabs","favicon","storage"],

"action": {

"default_title": "Open the VLT panel window.",

"default_icon": {

"16": "img/favicon-16x16.png",

"32": "img/favicon-32x32.png",

"48": "img/favicon-48x48.png",

"128": "img/favicon-128x128.png"

}

},

"background": {

"service_worker": "background.js",

"type": "module"

},

"icons": {

"16": "img/favicon-16x16.png",

"32": "img/favicon-32x32.png",

"48": "img/favicon-48x48.png",

"128": "img/favicon-128x128.png"

},

"options_ui": {

"page": "options/options.html",

"open_in_tab": true

}

}

I fully unloaded and loaded after the change

Hi there,

Do you have a public GitHub URL with your extension files?

I am happy to investigate that matter now.

Thanks,

No, I'd like to keep it private for now. Isn't this purely a manifest issue? What in the code are you thinking is causing it?

[Stefan vd]

Hi there,

I am using your manifest (with my latest correction). And I can clearly see my S logo on the Chrome://extensions page.
See the ZIP sample file here in the attachment.

Looks like the pngs I have are not compatible... I tried your png and it worked. Is there any information on how to generate a png that works with extensions?

Hi there,

I am glad to hear that you see my logo on the Chrome extensions page.

You just need to export it as "png". You can use Adobe Photoshop or Adobe Illustrator.
Or the online photo editor https://www.photopea.com/

Thanks,

Ah, I see what happened. I used a resizing tool that took the 128x128 and generated all of the other sizes but as .ico. I then changed the type to png... Whoops. It's working now when I manually generate pngs :)

Hi there,

Great!

Have a nice day there.

Thanks,
