Progressive Shopper is a Firefox extension designed to help users track the political contributions of companies they interact with online. This lifestyle-focused tool categorizes brands based on their political affiliations, using a color-coded flag system: blue for Democratic supporters, purple for bipartisan contributions, and red for Republican supporters. This visual indicator appears on the right side of the browser, providing immediate insight into a brand's political leanings.

In addition to the flags, users can click on them to access detailed information about the companies, including their political contributions and how they compare to competitors in terms of alignment with personal values. The extension promotes informed shopping decisions by enabling users to make choices that reflect their political beliefs, enhancing the shopping experience in a meaningful way.
