When reading feed articles, often you may want to read the web page that belongs to the article: some articles only contain the headline, and not the actual content. In this case, you need to visit the web page to read the complete article. Or perhaps an article links to some website, or you are reading a blog and want to comment on an entry. For these situations, Akregator contains a simple web browser. Whenever you follow a link in the article viewer, by default Akregator opens the link in new tab.
Note that the browser in Akregator is not intended to replace your favorite Web Browser. It is meant for reading articles, commenting on them, or following up a link quickly. It is not meant for browsing the web in general. It lacks many features fully-fledged web browsers offer.
