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 不断努力敦促网络社区坚决反对“禁止网络盗版法案”（Stop Online Piracy Act）和“保护知识产权法案”（Protect IP act）。这些法案一旦实施，将会给予美国政府和私人商业团体难以置信的审查权力，造成全球性的影响，削弱互联网的安全，遏制创新和全世界的投资。
