Browser maker Opera today announced the launch of version 68 of its flagship desktop browser. The marquee feature of the launch is the addition of a tracker blocker that will make it harder for advertisers and others to track you while you browse the web — and which has the additional benefit of speeding up your browsing session. Indeed, Opera argues that turning on both the tracking protection and the built-in ad blocker can speed up page loads by up to 23 percent.

The new tracking protection feature is off by default (as is the existing ad blocker). The tracking feature uses the EasyPrivacy Tracking Protection List, which has been around for quite a few years now.
