Introduction to RSS
When exploring the site you may run into some images. When you click on these images you will have the ability to add the news feeds from our forums, tutorials, startup database, and news directly to various services or applications. I will explain how this works below.
Bleeping Computer also support Firefox's livebookmarks feature. Basically you take a feed and bookmark it in Firefox. Then if you enter your bookmarks you will see a new folder corresponding to that rss feed. The contents of the folder will be the individual entries from the RSS feed. These will autoupdate as new content is added to the site. To access the Livebookmarks feature, visit any page of Bleeping Computer and you will see in the bottom right of your firefox window, on the status bar, and image that looks like this:
Simply click on that image to see a list of the Bleeping Computer livebookmarks and add it your favorites. When you add the livebookmark make sure you change the name to correspond to feeds name or firefox will automatically give it a generic name.
