Lolli is a subscription-based shopping extension for Firefox that allows users to earn bitcoin and cash back rewards while shopping online. By partnering with over 10,000 top retailers, including eBay, Adidas, and Booking.com, Lolli offers users the opportunity to earn up to 30% in rewards on their everyday purchases. The extension features browser notifications that alert users when they are on a partner site, ensuring they never miss out on potential rewards.

In addition to earning rewards, Lolli simplifies the cash-out process to a bank account. The extension also guides users towards alternative merchants when shopping on non-partner sites like Amazon, helping them secure bitcoin or cash back on similar products. Lolli prioritizes user privacy, stating that it does not track or sell user data, and generates revenue directly from its merchant partners.
