Frequently asked questions

How does Opera improve performance?

Opera has a feature called Opera Turbo, which uses server-side compression to give you better browsing speeds when you are on slow connections. If you are on dial-up or pay for your internet connection by data usage, Opera Turbo can save you money, too. Read more about Opera Turbo.

What about security? How does Opera protect my privacy?

Opera displays security badges, which give you a quick glance at the security of a page. If the browser detects anything potentially dangerous, it will display a page and security badge to warn you. Read more about security badges.

To ensure your privacy, there are ways you can control how websites monitor your web activities, and ways to keep your browsing habits and data private if you share a computer or account. You can manually set what information you want to share with specific sites. Read more about setting your web preferences.
