I'm making a Firefox extension but for some reason it's not working and I'm not exactly sure why. please help.
I'm trying to run this code in the extension's browser action popup:
<!DOCTYPE html>
<html>
<head>
<style>
html {
background-image: url('icon.jpeg');
background-repeat: repeat;
background-size: 50px 50px;
color: black;
font-family: 'Oswald', sans-serif;
}
</style>
</head>
<body>
<h3>TEST</h3>
<input id="input"><button id="button" onclick="console.log('hi')">ENTER</button>
</body>
</html>
but when I do it gives me this error:
Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”).
what does it mean and how can I fix it?
