Here is what ScribeFire has to say about itself:

ScribeFire is an extension for the Mozilla Firefox Web Browser that integrates with your browser to let you easily post to your blog: you can drag and drop formatted text from pages you are browsing, take notes, and post to your blog.

From what I have seen so far, I really like it. I can save all my accounts in one place and publish to any of them without having to login to each one. Pretty cool!
