Blackbird, the custom browser for African-Americans that debuted in 2008, launched a new version for Mac computers today. Previously available only for PCs, the browser already has a quarter of a million users.

Blackbird aims to offer a distinctively Black internet experience, and provides one-click access to a number of destinations of interest to its audience. The browser, which is built on top of the Mozilla Firefox interface, integrates email and social networking, points users toward Black-oriented news and video websites, and can optimize Google searches so that Black websites are pushed to the top of the results. It also includes job-searching tools and links to community service initiatives.

The Blackbird browser is free, supported by sponsors and advertising revenues.
