Kanvaso Rated 1 out of 5 stars
Since Power Twitter is not working any more against the new twitter, I switched to Kanvaso which is actually better than Power Twitter. You guys might want to try it too. It is http://kanvaso.com. It supports long tweet, image upload, url shortner, mute feature, video viewer, widget, and more. I love it.This review is for a previous version of the add-on (1.52).
