Comments at the popular video portal Youtube can get out of hand in both ways. It is not uncommon to find videos with hundreds or even thousands of comments on the video portal.

Opinion Cloud tries to bring order into chaos by creating a cloud of positive and negative opinions about the individual video. The cloud resembles a tag cloud known from web 2.0 websites and is basically the same deal. The tool will extract words from comments and display them in the cloud sorting them by positive and negative comments. A summary is shown at the top displaying the percentage of positive and negative opinions.

Words that have been used more frequently will be shown in a bigger font size to make it easier to weight the opinions. Each word that is listed in the cloud is at the same time a link to all comments that contain it. A click will display the comments on the same page with virtually no loading time.

Opinion Cloud is an add-on for the web browser Firefox that helps users, video creators and marketers on the Youtube video platform.

Youtube video download adds two links to one of the right panels that contain the url and embed links. The Download as MP4 and Download as 720p HD MP4 are displayed. They can be saved by right-clicking on one of the two links and selecting Save Link As from the context menu. One should note however that this is obviously only working if a HD video is available on Youtube. If there is no HD video the download will display the file as get_video or videoplayback which will not save the video at all. It is possible that one of the two Youtube video download links is working but there have been cases where none was working.

The Firefox add-on to download Youtube videos in high definition is currently experimental which means that you have to log into the Mozilla website to download and install the extension.
