To make CCleaner Browser your default browser, go to the Security & Privacy Center. When a banner appears at the top of the screen, click 'Make Default'. If a banner does not appear, CCleaner Browser might already be your default browser.
To ensure CCleaner Browser is your default browser:
- Open CCleaner Browser
- Click 'Menu' (the three dots) in the top-right corner of the screen, then select 'Settings'.
- Scroll to the 'Default browser' section, where 'CCleaner Browser is your default browser' should be visible
- If Secure Browser is not your default browser, click 'Make default'
