Download all media (images and video) in one click with the Bulk Media Downloader. You don't need to open every image or video link in a new tab, and you don't need to open a bunch of tabs. Just open the window and press the download button. You can even set it to automatically pause after each image or video is downloaded.

The extension is based on the popular FlashGot tool, which monitors changes in the HTTP URL and notifies you when a new link is detected. This way you don't need to constantly check your browser, and the download process won't be interrupted by network problems.
