ERR_FILE_NOT_FOUND, Google Chrome Extension

Question

Im trying to build google chrome extension. Below is my manifest file; I searched every where and took every step to resolve chrome-extension://ijkjkkkinepajpigeijodppknjgdooef/popup.html Error code: ERR_FILE_NOT_FOUND

{
"manifest_version": 2,
"update_url": "http://clients2.google.com/service/update2/crx",
"name": "Game Extension",
"version": "1.2.0",
"description": "Just for Fun",
"icons": {
"256": "img/icon.png"
},
"browser_action": {
"default_popup": "popup.html"
},
"permissions": [
"tabs",
"identity",
"http://*/*", 
"https://*/*"
],
"oauth2": {

"client_id": "232343423423PrivateClientKey",
"scopes": ["https://www.googleapis.com/auth/userinfo.email"] 
}
}

I have done everything , but issue is still there. Also,inside Extension

folder(**%LOCALAPPDATA%\Google\Chrome\User Data**),like other extensions my extension has no folder.

Please let me know what is going wrong.

Answer 1

Presumably, you are loading an unpacked extension.

Suppose you have a folder where your manifest.json file is. For the sake of an example, C:\Development\MyTestExtension

Then this folder becomes the root for the extension (in your case, chrome-extension://ijkjkkkinepajpigeijodppknjgdooef/)

So, if you declare popup.html as your, well, popup, Chrome will look for C:\Development\MyTestExtension\popup.html. Make sure this is exactly how that file is named: on Windows, file extensions are hidden by default and it's very easy to save a file as, say, popup.html.txt and not see the .txt part.

As for a folder in the profile: it's only for packaged extensions that you download and install, not development unpacked versions.
