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 BTS BT21 Cursor 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 BTS BT21 Cursor.

What does this mean for you?

  • Your BTS BT21 Cursor extension may stop working in the near future.
  • You might need to find an alternative extension for BTS BT21 Cursor that has been updated to Manifest V3.
  • If the developers update BTS BT21 Cursor to Manifest V3, you'll need to update your extension when it becomes available.
