Gather all information about video / gif and create a download button in the sidebar of videos / gif
Simple script to apply the download button to the current video on (https://redgifs.com)[redgifs.com] in their new v3 design. On changing the video the script removes old download buttons and recreates new one on the video you are watching. It depends on the browser how it behaves. Some will start downloading and others will open the video in a new tab.
