Blur is a simple yet effective browser tool that blocks the tracking capabilities of advertisers, social networks, and data-collection companies. Blur helps you restore your online privacy and regain control over who sees what you are doing online, stop annoying pop up ads and other targeted advertising, and load certain websites up to 4 times faster.

When you visit a website, that site tells your browser to contact all sorts of other companies to get information about what you do and who you are. Blur stops that data collection from happening by preventing your browser from communicating with these companies.

Requirements:
OS X 10.5+
