don’t let the word “add-on” fool you- Scribefire is as powerful, if not more so, as most of these standalone editors. Professional bloggers, in particular, who spend most of their time in the browser anyway, should find this useful. The advantage of being built into Firefox, of course, can also be a disadvantage- it isn’t a standalone application, and to use it you have to fire up Firefox- so it might not a good choice if you’re looking for something “offline”.
