Some useful Firefox extensions that made to the final round of Extend Firefox contest.

Deepest Sender is an inline Firefox blog editor client just like Performancing. Deepest Sender supports LiveJournal, Blogger (Atom), and WordPress platforms.

DownThemAll! lets you filter and download all the links contained in any web-page, and lets you pause and resume downloads from previous Firefox sessions.

Download Embedded lets you selectively download embedded web objects like movies, mp3s, flash swf, quicktime, and other embedded files. It is a nice alternative to Flashgot.

When the Download Embedded plugin detects an embedded object, a small red arrow will appear on the status bar at the bottom of your firefox window.
