A "heightened privileges browser" is a web browser that has been configured to run with increased privileges, allowing it to access and modify certain system resources that are normally restricted to standard web browsers. This can be useful for testing and debugging purposes, as it allows developers to more easily simulate the behavior of their code in different environments.  There are a few different ways that a web browser can be configured to run with heightened privileges, depending on the specific needs of the application and the capabilities of the browser. Some options might include:  Running the browser in a virtual machine or sandboxed environment  Installing a special browser extension or plugin that grants additional permissions  Setting command-line flags or environment variables to enable specific features or behaviors  It's important to note that running a web browser with heightened privileges can potentially be risky, as it can expose the system to security vulnerabilities or other types of attacks. As such, it is generally not recommended to use a heightened privileges browser for everyday web browsing or other non-technical tasks.
