I have setup LiveReload for Sublime Text 3 by following this guide .
I have installed the LiveReload Plugin for FireFox (it's enabled).
I have tested it with this simple HTML code:
<!DOCTYPE HTML>
<html>
<head>
</head>
<body>
<h1>Hello World!</h1>
</body>
</html>
For some weird reason it doesn't work. What might cause this issue?
