Extensions Issue - ContentScript & Premissions for an overlay
I'm currently developing an overlay for Google Chrome (A toolbar if you prefer), and i have some issues with and i can't understand the reason why.
So, basically i've created an extension with this manifest.json :
{
"background_page" : "background.html",
"browser_action" :
{
"default_icon" : "images/Extension.png"
},
"content_scripts":
[ {
"all_frames": true,
"css": ["css/overlay.css"],
"js": ["js/overlay.js"],
"matches": ["http://*/*"],
"run_at": "document_start"
} ],
"permissions" : ["tabs", "unlimitedStorage", "http://*/*"],
"name" : "MyOverlay",
"version" : "1.1",
"description" : "Sindar Overlay"
}
The concept is that my background.html page will call the jquery.js and overlay.js. Then on the initialization of overlay.js it will call the html page (overlay.html) by using
<iframe id="YourToolbarFrame" src="'+toolbarURL+'">
The problem is that when i'm trying to start the extension everything seem to be good, no compilation problem but i don't see my overlay. And when i'm just opening the html page all is ok, i see it. So i'm asking myself if the problem dont come from the contentscript or from the permissions but i dont know where it could come from...
Thanks in advance.

Currently you include overlay.js as a content script to all pages plus include it into a background page for some reason. You don't need a background page for this task. If you are doing this just to inject jquery the solution would be to download jquery.js and put it into your extension folder, then automatically inject it in the manifest.json:
//"background_page" : "background.html", - this is not needed
"content_scripts":
[ {
"all_frames": true,
"css": ["css/overlay.css"],
"js": ["js/jquery.js", "js/overlay.js"], //jquery included as well
"matches": ["http://*/*"],
"run_at": "document_start"
} ],
(besides a background page doesn't have visible body, so you inject your frame to an invisible page right now)
