Question

I m trying to "port" my Chrome-extension to Opera. My extension does nothing else but edits the DOM a little bit. In Chrome extension I use contentscript and based on my research the similar way for Opera is injected scripts. Anyway, the documentation doesn t really tell how should I use injected scripts.

I have the js-file in includes/ but seems like it doesn t include automatically. I also need to specify domains to inject the script on.

Currently my file has this content for testing purposes:

window.addEventListener( load , function() {
    alert( asd );
});

Any help is appreciated :)

Another resource you could read is the extension tutorial. However, looking at other extensions, I don t think you need to specify anything. Try putting a simple alert() in the script, or, even better, try inspecting the runtime with Dragonfly (Ctrl-Shift-I).

Check that you have your config.xml and index.html in place.
