Google is shutting down paid Chrome extensions offered on the Chrome Web Store, the company announced Wednesday.

That means that developers who are trying to monetize their extensions will have to do so with other payment-handling systems.

As of Monday, developers can no longer make new paid extensions, according to Google — though that’s cementing a policy that has already been in place since March.

And that policy follows a temporary suspension of publishing paid extensions in January after Google noticed an uptick in fraudulent transactions that “aim[ed] to exploit users.”

Google will gradually phase out other functionality over the coming months, and on February 1st, Google says that existing extensions can no longer charge customers using the Chrome Web Store’s payments system. Here’s the full timeline:

These aren’t the only notable changes to extensions that Google has made this year.

The company rolled out a number of policy updates in April intended to reduce spammy extensions, including banning multiple extensions that do the same thing, not allowing developers to manipulate reviews to try to get better placement for their extension, and forbidding extensions that abuse notifications.
