The initial plan is to block ads that use more than 4MB of bandwidth or consume CPU resources for at least 60 seconds.
Google Chrome would enhance your Web browsing experience by blocking resource-intensive ads by default
Google is found to have a new feature in the pipeline that would enable its Chrome browser to block resource-intensive ads by default. The search giant is internally calling the new feature "Heavy Ad Intervention" that is designed to limit "heavy ads" that often affect the Web browsing experience. Notably, the new development emerges in the midst of the ongoing changes that have been implemented to restrict third-party ad blockers on Chrome. The changes are planned through the Manifest V3 standard that projects the new DeclarativeNetRequest API as a replacement for the existing WebRequest API and aims to regulate ad blocking capabilities of browser extensions.
According to a new Chromium commit, Google is building the Heavy Ad Implementation that is currently planned to block ads that use more than 4MB of bandwidth or consume CPU resources for at least 60 seconds.
"This intervention unloads ads that are in the 0.1 percent of bandwidth usage, 0.1 percent of CPU usage per minute, and 0.1 percent of overall CPU time," Google engineer John Delaney described the feature in the commit that has been marked as "Work in Progress" and last updated on June 28.
Instead of simply blocking resource-intensive ads, the planned feature on Chrome informs users through a dedicated notice and provides a "Details" link to let the users learn more about the intervention, as noted by 9to5Google. The notice also specifies that the particular ad has been blocked because of its heavy resource-consuming nature.
It is clear whether Google will bring the new feature to the next Chrome update. However, the commit certainly confirms that the company is concerned about the ads that put a lot of load on system resources.
That being said, the planned feature isn't something that would block every single annoying ad on your browser. You would still need a separate ad blocker for such experience. Google, however, has its Manifest V3 standard in progress that is so far believed to restrict third-party blockers on Chrome.
As we mentioned, the new standard is aimed to replace the existing WebRequest API with the DeclarativeNetRequest API to limit ad blocking capabilities of browser extensions. Google faced outrage from extension developers for building the restrictive API, though it recently claimed that instead of "killing ad blockers" entirely, it is set to "make them safer."
