Import data from other browsers

Opera allows you to import browsing history, bookmarks, saved passwords, cookies, and more from your other browsers. If you want a more seamless experience between your browsers, importing browsing data can catch Opera up with what you’ve been doing in other apps.

To import browser data:

  1. Go to Settings (Preferences on Mac).
  2. Click Browser in the sidebar.
  3. Under Default browser, click the Import Bookmarks and Settings… button.

You can import browser data from Opera 12, Safari, or Google Chrome. Select the data you want to import and click Import.

Streamline development with developer tools

Developer tools are used for developing and debugging local and remote webpages. These include a DOM view of webpages and highlighting of elements. You can step through your JavaScript code, and quickly inspect changes to your CSS styles. You can debug your creations, and study your application’s impact on network resources. Developer tools allow remote debugging, making it possible to debug webpages as seen on a mobile phone or a television from your desktop.

The complete list of developer tools is too long to detail here. For more information, please review the developer tools user guide.

For Mac users, to open developer tools, select View Show Developer Menu. A new submenu called Developer will appear on the menu bar. To use the tools, select Developer > Developer Tools.

For Windows and Linux users, to open developer tools, go to O MenuDeveloperDeveloper Tools.

To close developer tools, click the X button on the upper-right corner of the developer tools window.

Configure proxy settings

A proxy server is a computer that can, for example: store local copies of pages for quick access, act as an interpreter between your browser and a special service, alter or monitor information exchange, or speed up web communication.

To change your proxy server settings:

  1. Go to Settings (Preferences on Mac).
  2. Click Browser in the sidebar.
  3. Under Network, click the Change proxy settings button.

All traffic using the respective protocol will go through the proxy server you specify. To use a proxy, you need to specify:

  • A protocol, such as HTTP
  • A web address, such as proxy.example.org or
  • A port number, such as 5000

You can get this information from your internet service provider (ISP), the host of your proxy server, or the documentation that comes with your proxy software.

You can specify whether you want the proxy used even for local servers by checking the Use proxy for local servers checkbox.

If your internet provider requires automatic proxy, please enter the web address provided by your ISP.

Enable advanced settings

Power users might want to view additional options in Opera’s preferences page. You can unlock advanced settings, such as controlling hardware acceleration or changing the number of columns that display on Speed Dial.

To enable advanced settings:

  1. Go to Settings (Preferences on Mac).
  2. Click Browser in the sidebar.
  3. Under Advanced settings, mark the box next to Show advanced settings.

When enabled, advanced settings appear with a gray dot.

Try new browser experiments

Opera allows you to test out experimental features, new capabilities, and alternative configurations for your browser. You can read about and enable experiments by navigating to opera:flags. Opera experiments are unstable and are not recommended for casual users. Enabling experimental features can compromise security and privacy and may delete data. If you choose to enable experimental features, you should proceed with caution on a properly backed-up computer.
