Deepest Sender is a client that will allow you to post to blogs from directly within Firefox. It is primarily a LiveJournal client, although it supports Blogger (GData) and WordPress (metaWeblog) too, with support for more stuff to come. Note that the actual Deepest Sender website will always have the most up to date version.
