We are the first major browser vendor to integrate an ad-blocking feature, but this development should be a no surprise to anyone given the rising popularity of ad-blocking software and even Apple allowing it on its platform.
Moreover, you can benchmark the load speed of the current webpage with and without the ad-blocker enabled.
Opera currently uses block lists from EasyList, both the regular EasyList to stop advertising and the EasyPrivacy list to stop trackers.
Our research shows that browsing with the Opera’s ad-blocking feature is on average 45% faster compared to browsing on Google Chrome with the AdBlock Plus extension. We think it’s pretty cool.
