Why Is My Subtle Tab Chrome Extension No Longer Supported?

Learn why your Subtle Tab Chrome extension may no longer be supported, what it means for you, and how to find an alternative.

If you got here, you probably have seen the following banner in the Chrome Web Store saying that your Subtle Tab extension may soon no longer be supported because it doesn't follow best practices for Chrome extensions.

Why is this happening?

Google is updating their browser extension store to improve security and performance. They're moving from Manifest V2 to Manifest V3, which is like upgrading from an old operating system to a new one for extensions.

"To better protect your privacy and security, Chrome and the Chrome Web Store require extensions to be up-to-date with new requirements. With this, Chrome may disable extensions that don't meet these requirements."

Google started informing extension developers and companies years ago that they should update their extensions to Manifest V3. This deadline is now coming to an end and extensions using the old V2 manifest will be removed.

The Subtle Tab extension is still using the older Manifest V2, which is deprecated for years and will soon be phased out. This change affects many popular extensions, not just Subtle Tab.
