In Pictures: First look, Opera 12 ups the ante

Do not track

Opera 12 can be set to prevent all websites from tracking your browsing activity, or only ones you specify. To turn this feature on to stop all websites from tracking, you go to Settings > Preferences > Advanced > Security and check “Ask websites not to track me.” Blocking a specific site from tracking you requires that you first visit it, right-click over a blank spot of the page, select “Edit site preferences” from the pop-up menu, Network, and then put in a check by “Ask websites not to track me.”
