``Google has begun to implement the controversial interface changes for browser extensions. These significantly limit adblockers such as Ublock Origin, Ghostery and Adblock Plus. Google recently integrated these changes into the development version of the Chrome browser (Chrome Canary). According to Google employee Simeon Vincent, the changes are still in the alpha stage, a stable release is not expected until next year according to Google.
With the Manifesto V3 ruleset, Google is planning major modifications to its Chrome browser and the open source version Chromium. The planned abolition of the blocking function of the webRequest API, which is used by advertising and tracking blockers, is particularly controversial. In the future, extensions will only be able to read browser requests, but not block, modify or redirect them.
As an alternative, the declarativeNetRequest API is to be introduced, in which the browser itself carries out the filtering - which, however, is limited to 150,000 elements. This is sufficient for the widespread Easylist filter list, but not for a combination of several extensive filter lists, such as is possible with Ublock Origin. Google only raised this restriction in June after protests, before that it was between 30,000 and 40,000 elements.``
