I'm attempting to create a simple firefox extension and am stumbling on what I'm allowed to do in a XUL window.
I'd like to use document.write or get a handle on a textarea to collect data and display it when a button is clicked.
Are there any tutorials on how to do this? From what I've been reading, people have suggested opening a new window and writing to it, but my goal is a persistent window at the bottom of the browser.
