Comment on WordPress SEO Plugin Options by SEO Dave.
It’s a known issue with Google Chrome, view my Article RSS Feed will look like HTML in Google Chrome and load with clickable links etc… in Firefox and Internet Explorer.
If you want Google Chrome to show the feeds like Firefox etc…. does you can install a Google Chrome RSS Feed Add On for example “RSS Subscription Extension (by Google)” which is free from the Google Chrome Web Store. Adding a Google Chrome Add On will only change what is seen for you, your visitors running Google Chrome will still see the HTML like output.
