Where's My Video is a free Chrome extension developed by Dogkiller87. It falls under the category of Browsers and specifically belongs to the Add-ons & Tools subcategory. This extension aims to help users find missing videos from their YouTube playlists.

Have you ever noticed that one of the videos in your YouTube playlist has gone missing? It can be frustrating to try and figure out which video is no longer available. That's where Where's My Video comes in. This extension allows users to easily find the missing videos' information, including their names and thumbnails.

The extension works by utilizing the URLs of the missing videos, which are still stored in the playlist even after they have been removed. By leveraging Google, the "vid" value from the URL, and various crawling websites, Where's My Video can help users identify which missing video has been deleted.

It's important to note that YouTube may remove deleted videos from your playlist after a certain period of time, typically a few weeks or months. Once this happens, Where's My Video will no longer be able to assist in finding the missing videos. However, until then, this extension can be a valuable tool for YouTube playlist management.
