Hello vhartke12, To set Firefox as your default browser on Android, tap the 3-dot menu button on the bottom right corner of your Firefox app, tap "Settings", then tap "Set as default browser". In the "Set Firefox as your default browser app?" pop-up, select Firefox and tap "Set As Default". Firefox is now your default browser. This is reflected in the first and second screenshots. If you want to change your default browser settings in the future, tap "Set as default browser", and you will be brought to Android's Default apps setting. Tap Browser app and in the "Default browser app" page, select the browser of your choice. This is reflected in the third and fourth screenshots. Kindly mark this answer as the solution(solved) if it managed to help you! If it did not, kindly report back so I can help!
