 Users are able to save all the tabs in a window as a Speed Dial group, manage the saved links, and open them all later if wished.When the Opera Turbo mode is enabled, Opera compresses requested web pages (but not HTTPS secure pages) by up to 80%, depending upon content, before sending it to the user.This process reduces the total amount of data sent and is particularly useful with slower Internet connections, making pages load faster, or when there are restrictions or costs dependent upon the amount of data transferred.
