Hey there! No worries, I'm here to help. If you're seeing the McAfee phishing pop-up on your Firefox for Android, it's likely coming from a security app on your device. You can try these steps to get rid of it: First, go to your device's Settings, then Apps or Application Manager. Look for the McAfee app or any other security app that might be causing this. Tap on it and then select "Uninstall." That should remove the pop-up. If you're still having trouble, you might need to disable or adjust the settings within the security app itself. Remember, keeping Firefox up-to-date and using our built-in privacy and security features should also help you stay safe online.
