Because converting video to mp3 requires a large FFMPEG server, the downloader website has safe and inoffensive advertisements, these ads are for paying the converter server rental.

If you are annoyed with advertisements, then this addon is not suitable for you, look for other addons in mozilla addons that do not have ads.

Thank you for understanding.
