Opera checks the block list using native code and fast algorithms, making the slowdown from checking negligible. But, many extensions spend a lot of time checking whether URLs or page elements occur in their block lists. When we started profiling the performance of adblockers, we found that commonly available block lists are of great quality and can block a lot of ads. Just to give some credit – CNET and TechCrunch appear to offer very good experience to their users with ads on – with only marginal delays in page loading. We added some sites there for you to test with – feel free to alter the list and add the sites you find that offer a good experience with ads enabled. You can click the gear icon in the pop-up to go there quickly. If you disable ad-blocking on a website, the website is added to an exception list, which you can manage from Opera’s settings. Moreover, you can benchmark the load speed of the current webpage with and without the ad-blocker enabled. This dialog will also reveal statistics showing how many ads you’re blocking on the current page, and how many you’ve blocked overall. To activate or deactivate ad-blocking for a specific website, simply click the shield icon in the address bar and flip the switch. While browsing, Opera will detect whether there are ads that can be blocked, and it will suggest enabling the ad-blocking feature. Opera’s ad-blocking feature is deactivated by default. We believe this will accelerate the change that the ad industry needs to pursue. This is why, together with the native ad-blocking feature, we also provide a tool to help advertisers and users understand the problem of heavy ads. It’s a good step, but what if ads could be better, less intrusive and not slow down the browsing so significantly? initiative for better ads but where are the better ads themselves? Instead, we see a primer on how to convince users to disable adblocking. It’s 2016, and we believe it’s time for ads to be lighter and faster. People are clearly sending a signal to brands and advertisers that the current situation must change. In a study conducted by PageFair/Adobe, the number of people using adblockers grew by 41% worldwide between 20, with 98% of those users on computers. That’s why more and more people use ad-blocking software. Another rising concern is privacy and tracking of your online behavior. Today, bloated online ads use more download bandwidth than ever, causing webpages to load more slowly, at times covering the content that you’re trying to see or trying to trick you into clicking “fake download buttons”. In time, though, they turned out to be one of the major annoyances of web browsing. Ever since then, ads have helped the web grow, giving people free access to millions of websites. The first online advertisement appeared on the web as early as in 1994. People really want ad-blocking technologyĪds have been an important part of the internet since its very beginning. 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. “Native” means unmatched speed vs extensions, since the blocking happens at the web engine level. Today, we wanted to share with you a native ad-blocking technology in our Developer channel for Opera for computers. If there were no bloated ads, some top websites would load up to 90% faster.
