Inject a div with content script not working

Question

I'm stuck with what seems to be really simple. I'm trying to inject a div of my own in every page the user visited, in a google chrome extention. I looked at examples on the web, but nothing seems to be working with me :s

Here's my manifest.json

{
"name": "My extension",
"version": "1.0",
"permissions": [
 "http://*/*", "tabs", "https://*/*"
],
"browser_action": {
 "default_title": "My extension",
 "default_icon": "icon.png"
},
"manifest_version": 2,
"content_scripts": [
 {
 "matches": ["http://*/*", "https://*/*"],
 "js": ["test.js"],
 "run_at": "document_end",
 "all_frames": true
 }
]
}

And my test.js

var newdiv = document.createElement('div'); 
newdiv.setAttribute('id','this_is_my_own_div');
document.body.appendChild(newdiv);

But I get nothing in source codes... My div's not created. How can I check if my test.js is running ? I can't understand why it is working with others and not with me :s Any help appreciate !

Answer 1

It worked try:

"browser_action": { "default_title": "My extension", "default_icon": "icon.png" },

instead of:

"browser_action": { "name": "My extension", "icons": ["icon.png"] }, 

• Sudarshan: It worked try "browser_action": { "default_title": "My extension", "default_icon": "icon.png" }, instead of "browser_action": { "name": "My extension", "icons": ["icon.png"] },
• Morgan: I might be missing someting here... That doesn't work either. Stil no "this_is_my_own_div" in the source page of amazon.com for example...
• Morgan: Hmm, apparently, it's working on my colleague's Mac. I run Version 23.0.1271.64 m on Windows 8, maybe this is why... Strange though...
