Google's "Manifest V2" Chrome extension phaseout next month is expected to impact the original uBlock Origin extension, which still uses the V2 framework and has 37 million users

The new MV3 architecture reflects Google's avowed desire to make browser extensions more performant, private, and secure. But the internet giant's attempt to do so has been bitterly contested by makers of privacy-protecting and content-blocking extensions, who have argued that the Chocolate Factory's new software architecture will lead to less effective privacy and content-filtering extensions.

For users of uBlock Origin, which runs on Manifest V2, "options" means using the less capable uBlock Origin Lite, which supports Manifest V3.

    The most salient of these is the blocking version of the webRequest API, which is used to intercept and alter network traffic prior to display.

    Under Manifest V2, it's what extension developers use to stop adverts, trackers, and other content appearing on pages, and prevent certain scripts from running.

    Li acknowledged the issue by noting the ways in which Google has been responsive, by adding support for user scripts, for offscreen documents that have access to the DOM API, and by increasing the number of rulesets in the declarativeNetRequest API (the replacement for webRequest) to 330,000 static rules and 30,000 dynamics ones.

    And by the beginning of 2025, when the API changes have been available for some time in the Chrome Stable channel, Manifest V2 extensions will stop working.
