Set Opera as the default browser

You can set Opera as your default browser so that Opera automatically opens when you request any webpages or information from the internet.

For Windows, the second time you run Opera, it displays a dialog asking if you want Opera to be your default browser. Select "OK" to confirm.

If you have cancelled this dialog previously, follow these steps to set Opera as the default browser:

Go to Preferences > Advanced > Programs.
Check the "Check if Opera is default browser on startup" option.
The next time you start Opera, answer “Yes” when the dialog asks you if you want Opera to be the default browser on your computer.
