I found it much easier to use than the BBComposer add-on. BBComposer (https://addons.mozilla.org/en-US/firefox/search/?q=bbcode) swapped the text area over into a "rich text" type display. It worked but was a pain to use and had random results under certain conditions.
The text formatting toolbar adds a button and a toolbar like the one below:
You can toggle the toolbar on and off by another button or via the Toolbars option under the view menu, so I just hide it when I don't use it. Most of the buttons work by selecting text and maybe adding parameters like a URL. I found it easy to use and clear about what I was editing. It also does Bulletin Board and Wiki code as well.
Don't forget that this is designed for text fields of one sort or another. This reply was formatted using it (though the screenshot is copied from Flickr). If you are editing a whole document, you'd have to use something else.
