I’m composing this post via [1] Performancing, a FireFox extension that allows the user to post straight from a window that slides up from the bottom of Firefox. It looks to be compatible with Blogger, TypePad, LiveJournal, Movable Type, all the biggies.It looks pretty slick, and has all the standard WYSIWYG buttons, so I can do stuff like bold, italics, underlining, text color, different font sizes, blockquotes, and links.

The only thing I’d add is a broader selection of buttons. Give me things like strikethrough and table creation.
