Google has changed its stance on upcoming Chrome Manifest V3 changes as benchmark shows they lied about performance hit. Catalin Cimpanu, writing for ZDNet: A study analyzing the performance of Chrome ad blocker extensions published on Friday has proven wrong claims made by Google developers last month, when a controversy broke out surrounding their decision to modify the Chrome browser in such a way that would have eventually killed off ad blockers and many other extensions. The study, carried out by the team behind the Ghostery ad blocker, found that ad blockers had sub-millisecond impact on Chrome’s network requests that could hardly be called a performance hit. Hours after the Ghostery team published its study and benchmark results, the Chrome team backtracked on their planned modifications. At the root of Ghostery’s benchmark into ad blocker performance stands Manifest V3, a new standard for developing Chrome extensions that Google announced last October.
