mozBlog is an open source blogging interface for the Mozilla browser. It implements the Blogger Application Programming Interface (Blogger API) in a sidebar component, enabling the user to maintain a blog via Extensible Markup Language Remote Procedure Calls (XML-RPC) messaging from the Mozilla sidebar.

mozBlog works with blogging tools that support the Blogger API, like Blogger, Moveable Type and Radio Userland. This site provides links to installation instructions, a user manual, the source code, a mailing list and screen shots of the interface.
