Install Firefox on Mac

1. Visit http://mozilla.org/firefox in any browser (for example, Apple Safari). It will automatically detect the platform and language on your computer and recommend the best edition(s) of Firefox for you.
2. Click the green download button to download Firefox.
3. Once the download has completed, the file (Firefox.dmg) should open by itself and pop open a Finder window containing the Firefox application. Drag the Firefox Icon on top of the Applications folder in order to copy it there.  

 

Note: If you do not see this window, click the Firefox.dmg file that you downloaded to open it.

4. After dragging Firefox to the Applications folder, hold down the control key while clicking in the window and select Eject "Firefox" from the menu.

5. You can add Firefox to your dock for easy access. Just open your Applications folder and drag Firefox to the dock.

Starting Firefox for the first time

When you first start up Firefox, you will be warned that you downloaded Firefox from the internet. Because you download Firefox from the official site, you can click Open.

Also, Firefox will not be your default browser and you'll be told about that. That means that when you open a link in your mail application, an Internet shortcut, or HTML document, it will not open in Firefox. If you want Firefox to do those things, click Yes to set it as your default browser. If not or you are just trying out Firefox, click No.
