As I mentioned, I previously used an IE extension to select text and "blog it". It would pull me right up into a new entry (though only if I logged in first) but it certainly helps me get entries up quickly that relate to a webpage. Now that I'm of the FireFox 3 set, I need a replacement for my old quick-blog system, and the third add-on I am trying is ScribeFire:

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.

Third? Yes, third. First I tried "DashBlog", I think it was called but that appeared to not do much of anything. Then I tried "ClipMarks", got much further but it doesn't appear to like the dasBlog Publishing API.
