How do you remove about blank on Firefox?

To remove the "about:blank" page from appearing in Firefox, you can change your homepage settings. Go to the menu (three horizontal lines in the top-right), select "Settings," then navigate to the "Home" section. Here, set your homepage to a specific website or choose "Firefox Home" instead of "about:blank." Additionally, ensure that no extensions are causing the issue and check your startup settings under the "General" tab to ensure the blank page isn't set to open on startup.
