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.
