The new feed, called the Explore Feed, has already been active on mobile devices and it sources items so the user may find things they are interested in, BT.com reported.
This items will be based on things they've previously liked or posts that are popular among their friends.
Although the new feed is working, users can find it under the section called Explore on the left of the desktop site.
Facebook is hoping the new feed will increase the amount of time users spend on the social media site as it battles against other networking giants including Snapchat and Instagram.
Although the feed itself has been in the testing phase, it's only now Facebook has maintained that its existence was only a test.
But the tech giant confirmed to TechCrunch that the feature was now no longer being tested and was officially rolled out on to the site's users worldwide.
Facebook said: "The feed was automatically customised for each person based on content that might be interesting to them."
The social media site, which was developed in 2004, has more than two billion users worldwide and last week it announced users in the US will now be able to order food directly from the site and mobile apps.
