- Virus. This app is the same as "Addoncrop video downloader" and "Foxified" -- all have the exact function and UI and share the same virus behaviour. What happens is: it *Does* work as a YouTube downloader, HOWEVER, it creates fake Google results. When you have the addon enabled and google something, it will show ads on the side of Google and about 10 fake results before showing you the real results. Furthermore, it tries to hide itself and make it difficult to uninstall. When you have the addon enabled, you will not be able to visit this webpage and it will automatically go to an error.
