You can install Tampermonkey to do this.
Note though that it uses the Greasemonkey-type headers and auto-executes your code when the DOM is ready. As in, you don't do the window.opera stuff and use addEventListener("DOMContentLoaded"... like you would do with Opera 12 user scripts. Also, the script code is managed inside the browser in the extension settings instead of files/directories. But, it's the same thing basically.
