Cómo convertir un manifiesto V2 en uno V3El archivo manifest.json requiere un formato ligeramente diferente para Manifest V3 y Manifest V2. En esta página, se describen los cambios que solo afectan al archivo manifest.json. Sin embargo, muchos de los cambios en las secuencias de comandos y en las páginas también requieren modificaciones en el manifiesto. Esos cambios están cubiertos por las tareas de migración que los requieren.Cambia el número de versión del manifiestoCambia el valor del campo "manifest_version" de 2 a 3. Manifest V2 { ... "manifest_version": 2 ...} Manifest V3 { ...

Como se implementó en Manifest V2, el campo "web_accessible_resources" hizo que los sitios web y los atacantes pudieran detectar extensiones si decidían exponer recursos. Esto generó oportunidades para la creación de huellas digitales o el acceso a recursos no intencional. Manifest V3 limita la exposición, ya que restringe qué sitios web y extensiones pueden acceder a los recursos de tu extensión. En lugar de proporcionar una lista de archivos como antes, ahora proporcionas un array de objetos, cada uno de los cuales asigna un conjunto de recursos a un conjunto de URLs o IDs de extensión.En el siguiente ejemplo, se comparan los recursos accesibles a la Web entre Manifest V2 y Manifest V3. En el manifiesto V2, todos los sitios web podían acceder a los recursos especificados de forma predeterminada. En el código de manifiesto V3 que se muestra a continuación, estos recursos solo están disponibles para mientras que solo ciertas imágenes están disponibles para todos los sitios web.Para obtener más información, consulta Recursos accesibles a través de la Web y Patrones de coincidencia.

Instructivo: Migra a Manifest V2

See pull request: #7387The newsGoogle recently announced that they will begin disabling Manifest V2 extensions in pre-stable versions of Chrome (Dev, Canary, and Beta) as early as June 2024, in Chrome 127 and later. Users impacted by the rollout will see Manifest V2 extensions automatically disabled in their browser and will no longer be able to install Manifest V2 extensions from the Chrome Web Store. "We expect it will take at least a month to observe and stabilize the changes in pre-stable before expanding the rollout to stable channel Chrome, where it will also gradually roll out over time."They have announced this already one year ago, but most likely this will actually happen this time.What does this mean for Scratch Addons?We will upload a Manifest V3 version of the extension to the Chrome Web Store before June 2024.As an indirect consequence, our minimum browser requirements will be affected as well. We currently support, to some extent, browsers versions as old as Chrome 80, released in 2020. We will increase the minum requirement to, at least, Chrome 92 (mid-2021). Older browsers won't be able to run the extension, as they don't know what a manifest three extension is, so it's not possible to show a "unsupported browser" screen in those cases.Plans on end-user browser supportThis is the plan I had in mind to keep up with Chrome's requirements.Add the "export settings" and "view settings as file" buttons to the Unsupported Browser page.This will allow users running old browser versions to export their settings before the extension goes away.We will release a typical MV2 update which will increase the minimum browser requirements to match the MV3 requirements.We will not change our minimum browser requirements as we upgrade to MV3. We will do it earlier. As I said, we can't show any screens or buttons to Chrome versions that don't support basic MV3 functionality, so we have to block them from using the extension earlier.Plans on local development and browser supportOur current MV2 extension has a manifest.json file at root which is accepted by both Chrome and Firefox. They both log warnings, but the raw extension folder as uploaded to GitHub is accepted by both.We plan to change the manifest_version of our manifest file to 3, so all local development will use an MV3 extension, both in Chrome and Firefox.This means contributors will need modern Firefox versions that support MV3, as well as. available for Chrome (both Manifest v2 and v3) not available for Firefox Manifest v2 but will be for Manifest v3 (track progress) webRequest. available for Chrome Manifest v2

Tutorial: migrazione a Manifest V2

Mozilla has reaffirmed its commitment to supporting both Manifest V2 and Manifest V3 for browser extensions, ensuring continued access to powerful privacy-preserving tools like ad blockers.This announcement comes as Google continues its phased deprecation of Manifest V2 in Chrome, which has already resulted in automatically disabling extensions that rely on the older framework, most notably, uBlock Origin, which counts 38 million users.Although Google developed Manifest V3 (MV3), other browsers like Firefox and Safari have also adopted it with their own implementations. The primary reason for this adoption is to maintain compatibility with Chrome extensions, which dominate the market. However, Mozilla has made key modifications to MV3, including keeping the blockingWebRequest API, ensuring that developers and users retain access to advanced privacy and content-filtering tools.Mozilla's statement, published earlier today, highlights its distinct approach to MV3. Unlike Chrome, which replaces blockingWebRequest with the more restrictive declarativeNetRequest API, Firefox will support both. This decision ensures that extension developers retain flexibility while allowing users to maintain their preferred browsing experience, including full-featured ad-blocking capabilities. The company emphasized that user choice and control over internet experiences are core to Mozilla's mission, citing Principle 5 of the Mozilla Manifesto — the belief that individuals should have the ability to shape their online experiences.Google abandons Manifest V2Meanwhile, Google has begun the widespread deactivation of Manifest V2-based extensions, including uBlock Origin, in Chrome. Reports from last week confirmed that some users are seeing their extensions disabled with a message stating they are no longer supported. While the rollout is gradual, Chrome users globally are encountering automatic removals, with limited options beyond switching to a Manifest V3-compatible alternative like uBlock Origin Lite. However, many privacy-conscious users argue that the Lite version lacks the robust filtering options of its predecessor.Mozilla's decision to support both Manifest V2 and V3 ensures that developers can continue to build powerful tools without restrictive API limitations. In contrast, Chrome users looking for similar functionality may need to explore third-party solutions or alternative browsers before Google completes the full phase-out of Manifest V2 by mid-2025.As Google accelerates its transition to Manifest V3, Mozilla's decision to maintain Manifest V2 support positions Firefox as one of the last remaining browsers where users can fully control their online experience. The Tor Browser is based on Firefox, so the same applies to that project. Both are on our list of the 12 most secure browsers that protect users' privacy, so

Tutorial: Migrate to Manifest V2

States: Individuals must have the ability to shape the internet and their own experiences on it. That philosophy drives our approach to Manifest V3.More creative possibilities for developers — We’ve introduced a broader range of APIs, including new AI functionality that allows extensions to run offline machine learning tasks directly in the browser.Support for both Manifest V2 and V3 — While some browsers are phasing out Manifest V2 entirely, Firefox is keeping it alongside Manifest V3. More tools for developers means more choice and innovation for users.Giving people choice and control on the internet has always been core to Mozilla. It’s all about making sure users have the freedom to shape their own experiences online.No limits on your extensions with Firefox​Google began phasing out Manifest V2 last year and plans to end support for extensions built on it by mid-2025. That change has real consequences: Chrome users are already losing access to uBlock Origin, one of the most popular ad blockers, because it relies on a Manifest V2 feature called blockingWebRequest.Google’s approach replaces blockingWebRequest with declarativeNetRequest, which limits how extensions can filter content. Since APIs define what extensions can and can’t do inside a browser, restricting certain APIs can limit what types of extensions are possible.Firefox, however, will continue supporting both blockingWebRequest and declarativeNetRequest — giving developers more flexibility and keeping powerful privacy tools available to users. We’ll keep you updated on what’s next for extensions in Firefox. In the meantime, check out addons.mozilla.org to explore thousands of ways to customize your Firefox.

Is there a manifest V2 to V3 converter? :

TL;DRGoogle Chrome is set to make sweeping changes to how extensions work via its transition to Manifest V3, but privacy advocates warn this could deal a major blow to popular tools like ad blockers.Over the next year, developers will scramble to update their extensions before Google begins disabling the existing Manifest V2 standard in mid-2024. Users meanwhile face uncertainty over whether their favourite plugins will retain full functionality or see their protections weakened.This controversial update from Google has been years in the making yet still faces criticism, and rightly so.A Primer on Browser Extensions - Manifest Standards: V2 vs V3Web browser extensions allow users to enhance their browsing experience through tools that can block ads or trackers, add functionality to websites, alter browser behavior and more. All major desktop browsers support extensions, though policies differ on capabilities between browsers like Chrome, Firefox, Safari and others.Regardless of the browser, all extensions require a basic configuration file called a manifest to function properly. This manifest.json describes the extension’s capabilities, permissions required, icons displayed and other identifying metadata. For example, here is uBlock Origins manifest fileThe current dominant version of this specification is Manifest V2, first introduced by Chrome in 2011. It has since become the de facto standard used by Chrome, Firefox and other browsers to ensure extensions work as expected and don’t access more user/system data than necessary for their function.Manifest versions act like programming language updates - they often tighten security, introduce new capabilities or reshape how existing features work. That’s precisely what Google aims to achieve with Manifest V3, though in a way that has serious implications for the ad blocking and privacy extension communities. Buried under claims of "security" and "privacy" are more questionable motives regarding Google's reliance on tracking users and serving ads.As YouTuber Nick puts it:"Google's main business model relies on serving ads and tracking users...their real interests are 'to use all this free stuff to track you, create a profile and push ads.'" This context is crucial to understanding their promotion of Manifest V3.At its core, Manifest V3 aims to replace WebRequest - the backbone API enabling ad blocking and content filtering extensions such as uBlock Origin - with a more limited alternative called DeclarativeNetRequest.Where WebRequest allows intercepting and reacting to network requests in real-time, DeclarativeNetRequest requires blacklists to be pre-defined without access to page contextual data. This directly threatens how popular privacy tools operate.AdGuard, a prominent ad blocking extension maker, helpfully summarized key differences:WebRequest provides raw access to HTTP headers and body, DeclarativeNetRequest does notWebRequest supports dynamic rules executed on every request, DeclarativeNetRequest requires static rules defined upfrontWebRequest responses can be modified, DeclarativeNetRequest cannot modify responsesDeclarativeNetRequest has strict quotas on rule sizeRestrictions on Cross-Origin

Manifest V2 to Manifest V3 is about to happen - Reddit

Im Dezember letzten Jahres haben wir die geplante Einstellung von Manifest V2 ausgesetzt, um auf das Feedback von Entwicklern zu reagieren und bessere Lösungen für Migrationsprobleme zu finden. Aufgrund dieses Feedbacks haben wir einige Änderungen an Manifest V3 vorgenommen, um diese Lücken zu schließen. Dazu gehören: Offscreen-Dokumente, die Erweiterungen DOM-Zugriff für eine Vielzahl von Szenarien wie die Audiowiedergabe bietenBessere Kontrolle über die Lebensdauer von Dienst-Workern für Erweiterungen, die Erweiterungs-APIs aufrufen oder über einen längeren Zeitraum Ereignisse empfangenNeue User Scripts API hinzugefügt, mit der Nutzer über Erweiterungen für Userscripts ihre Scripts sicherer ausführen könnenVerbesserte Unterstützung der Inhaltsfilterung durch großzügigere Limits in der declarativeNetRequest API für statische Regelsätze und dynamische RegelnWir haben nicht nur Lücken geschlossen, sondern auch neue Funktionen auf der Plattform hinzugefügt, z. B. die Seitenleiste API, die Anfang des Jahres eingeführt wurde, und die Leseliste API, die derzeit in der Betaphase ist. Viele dieser Änderungen haben wir vor Kurzem auf dem Dev Summit zum Thema Anzeigenfilterung besprochen und weitere Informationen zu den Änderungen und Verbesserungen geteilt, die wir auf Grundlage des Feedbacks vorgenommen haben. Durch diese Änderungen hat die Unterstützung für Manifest V3 in der Community der Erweiterungs-Entwickler deutlich zugenommen. Wir sind insbesondere ermutigt durch unseren fortlaufenden Dialog mit den Entwicklern von Erweiterungen zum Blockieren von Inhalten, die ursprünglich der Meinung waren, dass Manifest V3 ihre Fähigkeit beeinträchtigen könnte, Nutzern die von ihnen erwarteten Funktionen zur Verfügung zu stellen. „Bei Manifest V3 haben wir den enormen Aufwand beobachtet, den die Browserteams (insbesondere Chrome, aber auch andere Browser) in die Arbeit an einer einheitlichen Plattform stecken. Ich sehe, wie sie auf das Feedback von Erweiterungs-Entwicklern hören. Wie immer ist die Migration zu einer neuen Plattform ein großer Schritt. Wir sind jedoch zuversichtlich, dass die neue einheitliche Plattform dem gesamten Browsererweiterungen-Ökosystem erhebliche Vorteile bringen wird und dass Adblocker wie wir weiterhin leistungsfähig sein und sich weiter verbessern werden.“ – Andrey Meshkov, CTO von AdGuardNachdem wir diese Bedenken unserer Entwicklergemeinschaft ausgeräumt haben, sind wir bereit, die Umstellung auf Manifest V3 und die damit verbundenen höheren Sicherheits- und Datenschutzgarantien fortzusetzen. Daher setzen wir den Zeitplan für die Einstellung fort. Zeitplan für die EinstellungWir beginnen bereits im Juni 2024 mit der Deaktivierung von Manifest V2-Erweiterungen in Vorabversionen von Chrome (Entwickler, Canary und Beta) ab Chrome 127. Bei Nutzern, die von der Umstellung betroffen sind, werden Manifest V2-Erweiterungen in ihrem Browser automatisch deaktiviert. Sie können dann keine Manifest V2-Erweiterungen mehr über den Chrome Web Store installieren. Im Juni 2024 verlieren Manifest V2-Erweiterungen, die derzeit das Kennzeichen „Empfohlen“ haben, dieses im Chrome Web Store. Wir führen diese Änderung nach und nach ein und erfassen dabei Nutzerfeedback und Daten, um sicherzustellen, dass Chrome-Nutzer die Änderung verstehen und wissen, wie sie alternative, aktuelle Erweiterungen finden können.

The Year of Firefox : Manifest V2 to Manifest V3 is about to happen

Während des gesamten Roll-outs mit den Entwicklern kommunizieren und das Feedback während dieses Prozesses genau beobachten. Wir gehen davon aus, dass es mindestens einen Monat dauern wird, bis die Änderungen in der Vorabversion beobachtet und stabilisiert werden können, bevor das Roll-out auf den stabilen Chrome-Kanal ausgeweitet wird. Dort wird es dann nach und nach eingeführt. Die genaue Dauer kann je nach den erhobenen Daten variieren. Während dieser Zeit halten wir Sie über den Fortschritt auf dem Laufenden.Unternehmen, die die Richtlinie ExtensionManifestV2Availability verwenden, um die weitere Funktion von Manifest V2-Erweiterungen in ihrer Organisation zu gewährleisten, haben ein zusätzliches Jahr Zeit, also bis Juni 2025, um die Manifest V2-Erweiterungen in ihrer Organisation zu migrieren. Für Browser, in denen die Richtlinie aktiviert ist, hat die Einstellung bis dahin keine Auswirkungen. Nächste Schritte für Publisher von ErweiterungenWir empfehlen Anbietern von Erweiterungen, die noch Manifest V2-Erweiterungen veröffentlichen, dringend, die Migration zu Manifest V3 vor Juni 2024 abzuschließen. Wir haben einen Migrationsleitfaden veröffentlicht, in dem alles Wissenswerte für eine erfolgreiche Migration beschrieben ist. Eine Zusammenfassung der jüngsten Verbesserungen an der Erweiterungsplattform finden Sie in unseren Quartalsberichten vom Juli und Oktober. Wenn Sie während der Migration Fragen haben oder Probleme auftreten, wenden Sie sich bitte über unsere Supportkanäle an uns.In der Zwischenzeit werden wir weiterhin neue Funktionen veröffentlichen, um die Entwicklung von Erweiterungen insgesamt zu verbessern.Vielen Dank an alle, die Feedback gegeben haben. Das war für uns von unschätzbarem Wert, um die Plattform zu einem sichereren, leistungsstärkeren und datenschutzfreundlicheren Ökosystem für Erweiterungen weiterzuentwickeln.

Brave browser will support Manifest V2 extensions after Manifest

Google's latest Chrome update has disabled several widely used ad-blocking extensions, including uBlock Origin. This comes with the search giant moving to a new extension framework, Manifest V3. The update is being rolled out to improve security and privacy, but it has also removed key functionalities that ad blockers rely on.On Reddit and X (formerly Twitter), people reported Chrome disabling older extensions. A notification appears under the extensions tab in the browser's taskbar, informing users that the add-on has been turned off and is no longer supported.Manifest V3: Google's new extension frameworkManifest V3 is Google's updated standard for Chrome extensions. It aims to improve security, privacy and performance. The company states that the changes aim to reduce the risks of malicious extensions and limit potential data abuse. But the update also restricts the ability of extensions to modify web requests, a feature essential for ad blockers.Key extensions disabledAs Google phases out Manifest V2, Chrome users are seeing popular extensions, including uBlock Origin, become obsolete. Any extension that hasn't or cannot transition to Manifest V3 is being disabled, leaving users with limited alternatives, stated a report in the Verge.Impact on other browsersThe shift to Manifest V3 isn't limited to Chrome. Other Chromium-based browsers, such as Microsoft Edge, are also losing support for older extensions. Brave, a privacy-focused browser, has stated it can only provide limited support for Manifest V2 extensions once Google fully removes them from the Chrome Web Store, reported The Verge.Firefox and other browsers stand apartMozilla Firefox has said. available for Chrome (both Manifest v2 and v3) not available for Firefox Manifest v2 but will be for Manifest v3 (track progress) webRequest. available for Chrome Manifest v2 Manifest version 2 (Manifest V2 or just V2) to Manifest version 3 (Manifest V3 or just V3).

Manifest V2 vs. Manifest V3 in Browser Extensions - LinkedIn

What's this about?The transition from Manifest V2 to Manifest V3 comes with a fundamental change. In Manifest V2, extensions lived in a background page. Background pages managed the communication between extensions and web pages. Manifest V3 uses service workers instead.In this post, we delve into the problem of testing extension service workers. In particular, we take a look at how to make sure that our product works correctly in case a service worker gets suspended.Who are we?eyeo is a company dedicated to empowering a balanced and sustainable online value exchange for users, browsers, advertisers, and publishers. We have more than 300 million global ad-filtering users who allow the display of Acceptable Ads, an independently-derived ad standard that determines whether an ad is acceptable and nonintrusive.Our Extension Engine team provides ad-filtering technology that powers some of the most popular ad-blocking browser extensions on the market, like AdBlock and Adblock Plus with more than 110 million users worldwide. Additionally, we offer this technology as an open-source library, making it available to other ad-filtering browser extensions.What is a service worker?Extension service workers are a browser extension's central event handler. They run independently in the background. Broadly this is fine. We can do most of the things we need to do on a background page in the new service worker. But there are a few changes in comparison with background pages:Service workers terminate when not in use. This requires us to persist application states instead of relying on global variables. This means that any
