This is a great addon, saved me ton of work. But since FF is up to 3.0.x, I cannot use this wonderful tool, I had to reinstall back to 2.0.x to keep using it, so could you please update it!
Finally I couldn't wait any longer, I installed FF 3.0.1. And for people who need a tool just like this one, I have found another, it's called PTERODACTL. Basically it's the same thing, you can search the add-on page at FF website to find it.
