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.
