How to add firefox logo to titlebar drag space

more options

I'm able to remove the title bar drag space with .titlebar-spacer[type="pre-tabs"] {

 display: none !important;

} in userChrome.css. But I want to add a Firefox logo in there instead of removing it.

So for example, apply a background image to that empty space? If it's an image that is built-in to Firefox, that shouldn't be too difficult. Otherwise, you would need to drop the image file into your chrome folder along with your userChrome.css file -- don't use a URL to a website.

By the way, this is a great site for help with style rules: https://www.reddit.com/r/FirefoxCSS/
