Hi all,

I am developing a firefox extension which needs to add some html on the page it runs.

This element I will be writing needs to be decorated with css and also load some images.

I have both the css file and the images in the plugin, but I do not know how to reference them.

Do I need to insert the css file to the page I want to modify?

In the css file how can I reference the images that are in the extensions?

Thanks
