Firefox is a popular web browser known for its speed, privacy features, and robust extension ecosystem. For macOS users, Firefox offers a reliable alternative to Safari with additional customization options. This article will guide you through the process of installing Firefox on macOS, configuring it for optimal use, and running it via Terminal commands.

   • Open Safari or any other web browser.
   • Navigate to the official Firefox download page: https://www.mozilla.org/en-US/firefox/new/
   • Click on the "Download Now" button.
   • Once the download is complete, open the downloaded file (usually located in the Downloads folder).
   • Drag the Firefox application to the Applications folder.
   • Open Firefox from the Applications folder or use Spotlight (Cmd + Space) to search and open Firefox.

2. Running Firefox via Terminal:

   • Open the Terminal application on your Mac (found in Applications > Utilities).
