This was to be achieved by increasing limitations on the capabilities of extensions, such as removing the ability to load remote code like JavaScript. Google began work on MV3 in 2018, with the ostensible purpose of improving the security, privacy and performance of extensions. Is Google improving security or crippling it? With the looming cut-off date in sight, many users could be left seeking alternative extensions or simply switching web browsers in three months.

Many developers have observed that extensions updated to accommodate MV3 are often hobbled, minimalistic substitutes for their current MV2 counterparts – and while baseline ad blocking has been shown to be possible, it's repeatedly marred by significant compromises to advanced features and ease-of-use, with some developers reporting cases of 'ad flickering' while running MV3 browser extensions.Įxtensions dependent on MV2 can continue to be used under a certain Enterprise policy until June 2023, however, Chrome will otherwise stop running MV2 extensions and Chrome Web Store will no longer accept updates to existing MV2 extensions as of January 2023. So far, popular extensions such as Ghostery Privacy Ad Blocker, uBlock Origin, and Privacy Badger have all faced difficulty in achieving full compatibility with MV3, especially when it comes to features which enable in-depth logging or statistical analysis of browser requests. This especially applies to privacy extensions and extensions that specialise in filtering out undesired web content, such as ad blockers. Google's MV3 was created in a bid to 'increase user security and privacy,' however, many popular browser extensions have struggled to make a smooth transition to MV3 without having to significantly compromise on their intended functionality.

In January 2023 Google is cutting off legacy support for its pivotal application programming interface (API), Manifest V2 (MV2), encouraging adoption of the latest version of the API, Manifest V3 (MV3), instead. Next year, users of ad blockers and browser privacy tools may find their favourite Google Chrome extensions have stopped working, thanks to significant changes scheduled by Google.
