How does Opera improve performance?
Opera 15 has a new feature called Off-Road mode, 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, Off-Road mode compression can save you money, too.
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's Fraud and Malware Protection detects anything potentially dangerous, it will display a popup to warn you.
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.
You can read more about Opera's security and privacy features in our tutorials.
