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.

How do I delete items from my browsing history?

Opera keeps your history for as long or as short as you want and you can set this length of time in the browser preferences. See 'Delete private data' for more information.

To delete items from your history:

  1. From the main menu, select 'History'.
  2. Click the close/delete to the right of any history entry.

I love Opera! How do I make it my computer's default browser?

Setting Opera as your default browser is easy:

  1. From the main menu, select 'Settings'.
  2. Click 'Browser' in the sidebar.
  3. Under 'Default browser', click the 'Make Opera my default browser' button.

What's a private window?

Private windows erase any browsing data once you close the window - history, image cache, passwords, everything. You can browse more comfortably on public computers knowing your browsing activity and passwords are removed. Plan your surprise vacation with ease. For more information about private browsing, see 'Stay secure with private browsing'.

Where's the zoom slider? How do I zoom into a page?
