BubbleBox od Gigi_Girl_Dev

BubbleBox is a small virtual bubble-wrap toy for Firefox.

Open the extension to get a fresh sheet of interactive bubbles. Pop them one at a time, drag across several bubbles, or switch between Classic, Chain, Timed, and Zen modes. Chain mode can trigger nearby bubbles, while Timed mode gives you 30 seconds to pop as many as possible.

BubbleBox generates its interface and sounds locally. It does not require an account, external service, or network connection.
