i have firefox and when you come across a website with rss feeds, there will be a rss feeds button in the address bar, and when you click on it, it will make two types of feeds

Atom feed or RSS feed

this is the code to use in your html to make that happen

<link rel="alternate" type="application/atom+xml" title="Atom feed" href="http://www.example.com/feeed/1/" />
<link rel="alternate" type="application/rss+xml" title="RSS feed" href="http://www.example.com/feeed/1/" />
