I love anything powered by Mozilla, and Flock browser either. But it could be more brilliant if there were more options on customizing it.

Flock is a web-browser that has a built-in blogging tool. The blogging tool allows you to blog directly from the page, similarly to Scribefire, with a keyboard shortcut or a mouse click. However, the interface on Flock is a bit nicer, and has a slightly more seamless integration than in case of Scribefire and Firefox. Also you can use the web clipping tool to save and store clips of information in your browser.

Flock is an optimal tool for simple bloggers who dont need a lot of bells and whistles that come with other blogging editors.
