The End of Manifest V2

The transition from Manifest V2 to Manifest V3 for Chrome extensions has created a huge buzz in the developer community. Google is phasing out Manifest V2 in favor of the more secure and efficient Manifest V3, which promises improvements in security, performance, and privacy. If you’re a developer or an entrepreneur working with Chrome extensions, this shift represents both a challenge and a major opportunity.

Let’s dive into the details and explore what this transition means for you, especially with old Manifest V2 Chrome extensions being disabled.

What Is Manifest V2 and Why Is It Being Deprecated?

Manifest V2 was the dominant specification for Chrome extensions for years, allowing developers to extend the capabilities of the Chrome browser in various ways. However, as the web has evolved, so have the needs for enhanced security and performance.

This led to the introduction of Manifest V3, which addresses these concerns by implementing several improvements:

• More stringent permissions: Extensions have limited access to user data unless explicitly granted permission.
• Enhanced privacy: Content scripts and background pages are replaced with service workers, limiting persistent scripts that can run without user interaction.
• Improved performance: Manifest V3 reduces the resource footprint of extensions, enhancing the overall browser performance.

Google has already announced that old Manifest V2 Chrome extensions will be disabled starting in June 2024 for pre-stable versions of Chrome, with full deprecation expected by June 2025. This means that if you’re still relying on a Manifest V2 extension, it’s time to migrate or risk having your extension become obsolete.

The Impact of Old Manifest V2 Chrome Extensions Being Disabled

As of now, there are 5,000+ extensions that still use Manifest V2 on the Chrome Web Store. The deprecation of these old V2 extensions will leave significant gaps in the market, especially in key categories like productivity, security, and utilities.

For developers, this is a huge opportunity to step in and create new extensions or upgrade existing ones to Manifest V3, taking over the market spaces left by these deprecated V2 extensions.

Many users may not even realize their favorite extensions are still on Manifest V2, and when these old extensions get disabled, they’ll be looking for alternatives. Now is the time to act.

Key Dates for Manifest V2 Deprecation

• June 2024: Chrome will begin disabling Manifest V2 extensions on pre-stable channels (Beta, Dev, Canary).
• June 2025: Full support for Manifest V2 will end, and all V2 extensions will be disabled on stable versions of Chrome.

What Can Developers Do?

If you haven’t already, now is the time to migrate your extension from Manifest V2 to V3. Here’s how to get started:

• Review the Migration Guide: Google provides a detailed migration guide to help developers convert their extensions to Manifest V3.
• Test Early: Before the June 2024 deadline, ensure that your extension is fully functional in the latest versions of Chrome and that it adheres to the new Manifest V3 specifications.
• Innovate: Consider leveraging this opportunity to build new extensions that solve existing problems or improve upon outdated V2 solutions. Many V2 extensions with large user bases are ripe for replacement or acquisition.

Promote Your New Manifest V3 Extensions

Once you’ve transitioned to Manifest V3, make sure you promote your extension as a secure, future-proof alternative to V2 extensions. Highlight the security and performance improvements in your marketing materials to reassure users that your extension is aligned with the latest standards.

Additionally, stay updated with changes in the Chrome Web Store to ensure that your extension remains compliant and featured in search results. Utilizing keywords such as “Manifest V3 Chrome extension” or “Chrome extensions V2 to V3” can help increase visibility.
