Mozilla announces new privacy initiative called Polaris. Polaris is a privacy initiative built to pull together privacy efforts along with other privacy leaders in the industry. Mozilla engineers are evaluating Tor Projects changes to Firefox to determine if changes to our platform codebase can enable Tor to work more quickly and easily. The second experiment (which is our first in-product Polaris experiment) seeks to offer a feature that protects those users that want to be free from invasive tracking without penalizing advertisers and content sites.”]
