While most tech companies have decided to either quietly support, oppose, or stay out of the fight altogether, Mozilla (who makes Firefox) has come out strongly against the Cyber Intelligence Sharing and Protection Act (CISPA)
"While we wholeheartedly support a more secure Internet, CISPA has a broad and alarming reach that goes far beyond Internet security,” Mozilla’s Privacy and Public Policy lead (we assume Alex Fowler) told Forbes in a statement. "The bill infringes on our privacy, includes vague definitions of cybersecurity, and grants immunities to companies and government that are too broad around information misuse. We hope the Senate takes the time to fully and openly consider these issues with stakeholder input before moving forward with this legislation."
Interestingly enough Google has not taken a position on the bill, telling Forbes that "We think this is an important issue and we’re watching the process closely but we haven’t taken a formal position on any specific legislation."
Mozilla has no problem with being vocal about legislation that it thinks will harm the Internet: it came out strongly against SOPA and PIPA in January and joined other tech companies like Google, Reddit, and Facebook in their online protest against the bills.
