Mozilla was instrumental in the movement to motivate the Web community to act against the Stop Online Piracy Act and the Protect IP act. These laws, had they gone into effect, would have given the US government and private businesses incredible censorship powers that would have global ramifications, weaken the Internet's security and discourage innovation and investment worldwide.
Mozilla byla výrazná v protestu webové komunity proti Stop Online Piracy Act a Protect IP act. Tyto zákony, kdyby vstoupily v platnost, by daly vládě USA a soukromým společnostem velké možnosti cenzury, které by měly globální důsledky a oslabily by Internet v oblastech jako je bezpečnost a odrazovaly by inovace či investice po celém světě.
