Search for a Cause is a Firefox extension designed to turn your online searches into meaningful contributions to various charitable causes. By setting this extension as your default search engine, each search you perform generates revenue from ads, which is then donated to nonprofits dedicated to environmental and humanitarian efforts. Users have collectively raised over $1.5 million for charity simply by using this tool, making it a unique and impactful addition to the browsing experience.

The extension prioritizes user privacy, ensuring that while it tracks relevant profile information like the number of searches, it does not store individual search queries. The search results and advertisements are provided by a partner, which may collect anonymized data for improving service quality. Overall, Search for a Cause not only enhances your browsing capabilities but also empowers users to contribute positively to society with every search.
