Question

I’m following this tutorial to create a simple Hello World extension for Chrome:
http://code.google.com/chrome/extensions/getstarted.html
I have followed all the steps in that tutorial, and although I get to see the icon in the toolbar button, when I click the button I see a popup document with this error:

This webpage is not found No webpage was found for the web address:
chrome-extension://mblkllehamdcncminlelggjfcbmkflbj/popup.html Error 6
(net::ERR_FILE_NOT_FOUND): The file or directory could not be found.

I have the popup.html and popup.js files in the same folder than the icon
Here’s my manifest.json contents:

{
  "name": "My First Extension",
  "version": "1.0",
  "manifest_version": 2,
  "description": "The first extension that I made.",
   "browser_action": {
    "default_icon": "icon.png",
    "default_popup": "popup.html"
  },
  "permissions": [
    "http://api.flickr.com/"
  ]
}

Any idea what’s wrong? (I’ve been googling for quite a while without success, looks like the point where I’m stuck at is no problem for anyone else…)

Thanks in advance!

Ooops…

Forget about this lame question.

My popup.html file had a blank space at the beginning of the file name ( ” popup.html” ) because of the copy-paste. I removed it and it worked perfectly.
