Google Chrome, by default, does not support RSS feeds. You will need to install an extension so that it will handle them properly. Go to Settings, Extensions, Get More Extensions and search for "RSS", or just browse to:
https://chrome.google.com/webstore/search-extensions/rss?hl=en-US
The first in the list is probably RSS Subscription Extension (by Google), the one offered by Google, but there are dozens to choose from.
Microsoft Internet Explorer, Firefox, Opera and Safari all support RSS feeds by default. If you have trouble, or are using another browser, try searching your browser name and "RSS" in Google or Bing for assistance.
