Enrutador de Descargas

This extension will route downloaded files to specified folders on your computer. Can be done based on download url, MIME, or regex of content name. There is an option to have the downloaded content to overwrite the name if a duplicate is found.

I simply added the overwrite function to fit desired needs.
