dアニメ 新規タブツール is a free Chrome add-on developed by pluscreate. This tool allows users to play videos in new tabs within the same window, and it also enables the simultaneous playback of multiple videos.

With this add-on, when a user plays a video, it will open in a new tab instead of a new window. This provides a more streamlined browsing experience for users who prefer to keep their video playback within the same window.

Additionally, if a user attempts to play another video while already watching one, the new video will be displayed and played in a separate tab, allowing for the simultaneous viewing of multiple videos.

Please note that this add-on does not function on the top page.

Overall, dアニメ 新規タブツール is a useful tool for Chrome users who want to watch videos in new tabs within the same window and have the ability to play multiple videos simultaneously.
