The new version of the browser Mozilla Firefox 109, available from this Tuesday, January 17 for Windows, Linux, iOS and Android, includes support for Manifest Version 3 (V3) and integrates a button for managing extensions.

Manifest V3 is the new version of Google’s browser extensions platform, in which developers of application programming interfaces (APIs) publish their modifications and additional functions.

The company planned to roll out Manifest V3 gradually in early 2023 to replace the previous version, Manifest V2. However, this implementation has been postponed, no set release date,as shown on its developer page.

Regarding the previous one, Manifest V3 promises increase security of this service, by offering greater transparency with the permissions requested by the extensions that are installed in the browser.

With this update, in addition, the badges will be introduced, with which Google seeks to reinforce the extensions with best practices and that will allow users to know the identity of the creators of the extension and, even, if the experience it offers complies with the rules. from the platform.

Since the presentation of this version, the role that Manifest V3 will have with ad blockers –which prevent pop-up windows with promotions from appearing on the pages that are visited– has been questioned, since makes it difficult for these extensions to work.

Mozilla has highlighted this issue with the release of version 109 of the Firefox browser, which supports the Manifest Version 3 extension by default, although it continues to support the previous version, Manifest V2.

The company has commented that users can rest assured that, despite these changes, “the Manifest V3 implementation of Firefox ensures users can access privacy tools most effective extensions available, such as uBlock Origin and other extensions that block content and preserve privacy.”

He has also indicated that “this important update It also ushers in an exciting UI change in the form of a new “extensions” button, which provides the ability to inspect and control which extensions have permissions to access the websites being visited.

This new extensions button allows users to remove and manage extensions and their permissions directly from the toolbar. Thus, those that have been installed will appear in the extensions panel. If they don’t show up here, they may already be pinned to the toolbar.

Mozilla has commented that once an extension has been downloaded and a web page requires your permissions to function properly, a notification will appear with a green dot, either under the extensions button or under the extension icon itself.

It should be remembered that Google announced in mid-December that it had delayed the start of tests for the withdrawal of support for Manifest V2 in its browser extensions platform and that would reveal its roadmap in March of this year.

The company justified this change in plans due to the problems it was encountering in the migration and showed its commitment to give developers “enough time to update and test your extensions” after the release of Manifest V3 capabilities before disabling Manifest V2.
