I'm trying to write a chrome extension that uses a CSS file, but it just does not get injected. The manifest file is pretty straight forward
{
"manifest_version": 2,
"name": "Youtube Embed Performance",
"description": "",
"version": "1.0",
"permissions": ["https://redcursor.net/channels/18181"],
"content_scripts": [
{
"matches" : ["https://redcursor.net/channels/18181"],
"css" : ["youtube.css"],
"js" : ["youtube.js"],
"run_at" : "document_start"
}
]
}
The script appears in the Sources tab as part of my extension (and gets executed). The CSS won't appear there.
