JavaScript

Hello everyone! So I was just wondering if it was easy to develop a very simple Firefox plugin where you could click a button, and it would execute some Javascript code!

Please note that I have never developed any kind of plugin for firefox, I just want to know if that is an easy task to do (like less than an hour)
