What is Firefox?

Firefox is a desktop web browser for Mac that helps you access websites, sign in to online accounts, use web apps, and manage everyday browsing tasks. It is developed by Mozilla Corporation and is used by people who want a full-featured browser for work, school, and personal use. Common uses include tabbed browsing, bookmarks, saved passwords, downloads, web searching, and syncing browsing data across devices with a Firefox account. Firefox also supports add-ons, private browsing, and built-in controls that block many common tracking technologies. On macOS, it works as a native browser app and can be set as your default browser for opening links from other apps.

Safety overview

Status: Safe

Firefox is a well-known browser from Mozilla Corporation and its normal behavior includes network access, storing browsing data, downloading files, and offering to become the default browser. It may request access related to downloads, notifications, camera, microphone, or location when websites ask for those features. Those requests are consistent with browser use, but you should review site permissions regularly and keep the browser updated, especially if you use extensions or store passwords in it.

Recommendation: Keep Firefox if you use it for everyday browsing, web apps, or account syncing on your Mac. If you no longer use it, you can remove the app, but you may also want to review whether you want to keep saved profiles, downloads history, and other local browsing data.
