Solalita

Solalita is a Firefox add-on that allows you to donate to charity without spending any of your time or money. Each time you open a new tab, Solalita's incredible new tab page filled with custom widgets, pictures, and non-intrusive ads helps generate ad revenue, which is then donated to the cause you are supporting. By simply browsing the internet, you can make a positive impact on building libraries, making clean water accessible, and more.
