I’ve been wondering about an interesting orange icon I have seen on the right hand side of the URL display in Firefox, which seemed to always be there for WordPress sites. Thanks to Tom at TuttleSVC, I know it is now implemented in Mozilla and Microoft browsers to indicate a site has an RSS feed available.
If you click the icon (in FireFox) you get the dialog box seen when you select to bookmark a page. This adds a Live BookMark that updates the links when the RSS feed changes, providing a handy way to follow important sites, or having your browser bookmarks act like an RSS title aggregator:
From poking around, the browser is determining if a site has a feed by looking at the LINK tags in the source HEAD, e.g.
<link rel="alternate" type="application/rss+xml" title="RSS 2.0"
Not earth shattering news, but now I can stop my curiosity at the orange icon.
