Mozilla Firefox for Mac is a web browser, specifically a version of the popular Firefox browser designed and optimized for macOS operating systems (like macOS Ventura, Monterey, Big Sur, etc.). It offers the same core functionality as the Windows or Linux versions, such as browsing the internet, managing bookmarks, using extensions, and maintaining privacy settings, but with a user interface and features tailored to the Mac environment. This includes things like integration with macOS features and a design consistent with other Mac applications.
