Performancing for Firefox

So there’s this pretty nice application for firefox called Performancing that lets you blog directly from Firefox.  I don’t know about everyone else, but I’ve always bloged directly from Firefox. The only difference is that with Performancing you get a nice little horizontal side bar to do it in.  The extensions you can make in Firefox are really nice.  Although I’m not normally a fan of toolbars the Google toolbar is very useful.  The things I use the most are the spell checker and the page translater.  It also has a function that translates words from English to to other languages when you hover your mouse over them.  I wish I could get that functionality for Japanese to English.
