I’ve been using browser sandboxes for a few years now, and one of the easiest tools I’ve worked with is Sandboxie Plus.
To sandbox your web browser with Sandboxie Plus, first download and install the software from sandboxie-plus.org. Once it’s installed, open the application and click “Create New Sandbox.” Give it a name like “Browser” to keep things organized. Then, right-click your browser icon (like Chrome or Firefox), select “Run Sandboxed,” and choose your newly created sandbox. This launches your browser in a controlled environment—so if a site tries to do something shady, it won’t affect your actual system.
