## 🚫 www. is deprecated
### Correct URL to no-www URL.

This userscript queries given website for no-www URL and redirects to URL without www subdomain.

Use of the www subdomain is redundant and time consuming to communicate. The internet, media, and society are all better off without it. Please visit [no-www.org](https://no-www.org/) for more information.
