Thanks to CTOnews.com netizen Coje_He for the clue delivery! CTOnews.com, November 21 / PRNewswire-FirstCall-Asianet /-- Mozilla has previously announced that Firefox browsers will fully embrace Manifest V3 (MV3), the next iteration of the Web extension platform by the end of 2022, and this new feature has been tested.

According to Mozilla's official blog, MV3 has brought user-oriented changes to Firefox, including a unified extension button to manage installed and enabled browser extension permissions (source controls), providing Firefox users with control over extended access to their browsers. This button has been added to Nightly in Firefox 107and will be provided with MV3 in Firefox 109( January 17, 2023).

In addition, starting from November 21, 2022, Firefox browsers will open the submission of MV3 extensions, and the retirement time of MV2 will be announced after a follow-up evaluation.

CTOnews.com learned that in MV2, host permissions are granted by the user at installation time, and there is no easy way for the user to change this setting (uninstall / reinstall and select different permissions). However, with the new Unified extension button in MV3 in Firefox, users can easily access and control which extensions can access web pages at any time. Users are free to grant continuous access to the site, or to make a choice each time they visit.

According to the introduction, the button panel will show the extensions that the user has installed and enabled and their current permission status. In addition to managing host permissions, the panel allows users to manage, delete, or report extensions. The MV2 extension will also appear in the panel, but users will not be able to perform operations on MV2 host permissions because these permissions are granted at installation time, and this selection cannot be undone in MV2 without uninstalling the extension and restarting it.

It is worth mentioning that one of the most controversial changes in MV3 is the removal of Web Request API to support the new declarative network request API (Declarative Net Request API). Developers have criticized the change a lot because it deprives many extended features and reduces efficiency, represented by Google's Chrome browser. While Mozilla chooses to keep Web Request API, it also supports declarative network requests.
