FireSoup

FireSoup allows posting to the soup.io tumblelogging platform. It behaves similar to the official soup.io bookmarklet and even opens up the same service page, but the actual opening of the post window (including the communication of necessary page information) happens by means of chrome instead of Javascript injected into the current page, the latter which does not work if you happen to have JavaScript blocked on the current page (e.g. by the means of NoScript or similar addons).
