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. From the main menu, select Settings.
  2. Click Browser on the sidebar.
  3. Under Default browser, click the Import Bookmarks and Settingsā€¦ 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 pages. These include a DOM view of pages 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 pages 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.

To open developer tools, select More tools > Show developer menu. A new submenu called Developer will appear in the main menu. To use the tools, select Developer > Developer tools.

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

Enable advanced settings

Power users might want to view additional options in Opera's settings 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. From the main menu, select Settings.
  2. Click Browser on 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.
