Caramel (Open Beta) 作者： Devino

Caramel is the first fully open-source coupon and cashback extension built for Firefox.

• 100 % open-source. The full code is on GitHub; security pros audit every release.
• Privacy-first. We request only the tabs we need while you shop, nothing else.
• Real savings. Auto-tests every code and shows exactly what you keep.
• Creator-friendly. We never overwrite affiliate links; that stays with the rightful owner.
• Community-powered. Developers and shoppers improve Caramel together.
