As Google Chrome transitions to Manifest V3, the implications for browser extensions are becoming increasingly significant. This shift raises questions about the future of popular extensions, particularly uBlock Origin, which relies heavily on the more permissive Manifest V2. Users who depend on such extensions may find themselves contemplating a switch to alternative browsers that continue to support Manifest V2.
4 Firefox
For those seeking a modern browser that still embraces Manifest V2, Mozilla’s Firefox stands out as a prime option. Utilizing a reverse-engineered version of Chrome’s extensions API, Firefox allows users to access a wide array of Chrome extensions through its official repository. While Mozilla has announced plans to adopt Manifest V3 in the future, it has also committed to maintaining support for Manifest V2, ensuring that users can continue to utilize essential extensions that require the webRequest API for content blocking.
3 Vivaldi
Vivaldi, another contender in the browser arena, has pledged to support Manifest V2 until its eventual removal from Chromium in June 2025. However, this timeline offers limited respite for users, as the transition away from Manifest V2 is rapidly approaching. Vivaldi’s reliance on the Chrome Web Store for extension installations raises concerns about the accessibility of Manifest V2 extensions, which Google plans to obscure in the near future.
2 Microsoft Edge
Microsoft Edge finds itself in a unique position, having embraced Manifest V3 while still allowing users to install Manifest V2 extensions. Although Microsoft is no longer accepting new Manifest V2 extensions, existing ones can still be updated and utilized. While this may provide temporary relief, the long-term viability of Edge as a platform for Manifest V2 extensions remains uncertain.
1 Brave
Brave Browser, while not offering full support for Manifest V2, has indicated a commitment to specific extensions like uBlock Origin. The company’s leadership has hinted that support may only extend until June 2025, leaving users in a precarious position. Although Brave’s focus on privacy and ad-blocking features appeals to many, the uncertainty surrounding extension support could be a deterrent for those reliant on a broader range of plugins.
