? I get a lot of questions every day and here is a one from today... Question: How can I make Firefox the default browser on my Mac when opening links from my email program and others? Answer: You can set Firefox as your default browser by running Safari (I know it sounds weird), then... Select Safari Menu, Preferences... Select the General Icon Click on Default Web Browser pop-up menu Select Firefox Close the Preferences window Quite Safari From now on, clicking a link in your email or other program will use Firefox instead of Safari as the default browser.
