10 Most Useful Opera Widgets

Opera widgets are free and small web programs that run outside the browser and make the desktop experience more fun. They can also be useful providing easy and quick access to information or services. There are about 1300 widgets of many kinds. Examples include news feeds, different games, pixel rulers, world web cams, search tools and many others.
Installing widgets in Opera is very easy. To do this, use the Widgets panel or menu and select "Add widget". This will open a web page where you can choose and download widgets that Opera will install automatically.
