Google to Enforce Manifest V3 Extension Program Standard Again
TapTechNews May 31 - Google officially announced on May 30 that it will again enforce the Manifest V3 extension program standard.
Starting from June 3, in Chrome Beta, Dev and Canary versions, if users still have Manifest V2 extensions installed, they may see a warning banner when accessing the extension management page, notifying them that some extensions will no longer be supported soon. At the same time, extensions with Featured badges that are still using Manifest V2 will lose their badges.
In addition, Google will gradually disable these extensions in the next few months. Users will be directed to the Chrome Web Store, where they will be recommended to use alternative extensions that comply with the Manifest V3 standard. Within a short time after disabling the extensions, users can still reopen their Manifest V2 extensions, but this switch function will also disappear over time.
Google says that the goal of Manifest V3 is to protect existing functions while enhancing the security, privacy, performance and credibility of the entire extension ecosystem, including adding support for user scripts and introducing off-screen documents to allow extensions to use the DOM API from the background context. Based on the input from the extension community, the Manifest V3 standard also increased the number of rule sets of declarativeNetRequest, allowing extensions to bundle up to 330,000 static rules and dynamically add another 30,000 rules.
Regarding issues such as the elimination of Manifest V2 extensions severely affecting ad blockers, Google said that more than 85% of actively maintained extensions in the Chrome Web Store are using the Manifest V3 standard, and many popular ad blockers also offer Manifest V3 versions.
TapTechNews previously reported that Google had been pressured to announce that it would shelve the plan and postpone the migration to Manifest V3. Google product manager David Li said that Google plans to disable Manifest V2 extensions in the Chrome stable version to be released最快 in June 2024.
