It’s easy with Safe Surfer to install an effective porn blocker for a Firefox web browser. Along with protecting your privacy, we use our behind-the-scenes technology to block porn and other harmful online content. Let’s get started with installing protection. Before we get started, we recommend that you consider using one of our system-wide installation methods instead. Protection installed within the Firefox web browser can be turned off, and other built-in web browsers (for example, Microsoft Edge or Samsung Internet) would otherwise not be protected.
