Start your PlayStation 3's web browser. You can do this by navigating to the "Network" category on your PS3's main menu and selecting the "Internet" option.
Point your web browser to a website that uses Flash. YouTube, at www.youtube.com, is a good example.
Let the page load. Depending on your Internet connectio, this could take a few seconds.
Click "OK" when the box reading "Install Missing Plugin" appears on screen. You will know the update is complete when YouTube videos then begin to load.
