Is it easy to develop a simple Firefox plugin (JS injection)

Question

So I was just wondering if it is 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 plugin for firefox, I just want to know if it needs a simple task (for example, less than an hour)

I would also like to redistribute this very simple plugin to my friends.

Answer 1

If you just want to do this, you can create a Greasemonkey plugin . It is really easy.

Or, if you want to create an extension, you can use something like:
