Oasis browser, built on Firefox technology, collects technical and interaction data and sends it to Mozilla to understand how you use the browser and to make it better. This data helps Mozilla fix bugs, improve performance, and add features that people love. Understanding these settings helps you maintain control over your privacy while contributing to browser improvement.
