Firefox Extension: Get selected text

Question

I am working on a simple Firefox Extension and I want to get the selected text. I tried this:

var WordCount = {
    /* ... */
    changeSelected: function() {

Your problem is that document.commandDispatcher.focusedWindow is going to be pointing to a chrome window, where I suspect you actually want a content window. Try replacing that with content.getSelection()
