"name": "Although Microsoft Edge, Mozilla Firefox and Apple Safari have all adopted MV3, they have done so with their own implementation modifications, allowing users greater freedom while still benefiting from the security enhancements.\n\nStill, support for MV2 is the only way to go for older add-ons, and Firefox reiterated via an announcement that it will continue to support it in the foreseeable future. \"While some browsers are phasing out Manifest V2 entirely, Firefox is keeping it alongside Manifest V3,\" said Mozilla.\n\nSpecifically, the internet company said it would continue to support both the 'blockingWebRequest' and 'declarativeNetRequest' APIs, corresponding to MV3 and MV2, respectively, allowing extensions like uBlock Origin to continue working as usual.\n\nFirefox has not stated how long this support will continue, but as long as there are powerful add-ons enhancing user privacy and security, Mozilla should continue to have strong reasons to extend support for Manifest V2.",
