Firefox - Debugger Client for Cookie Access

A researcher created a tool that uses Firefox's debugging API (a set of commands for controlling Firefox remotely) to extract cookies (small files that store login information and preferences) from the browser, which is useful when an attacker doesn't have administrator access or user credentials. The tool works by connecting to Firefox's debug server, sending JavaScript commands to access the Services.cookies.cookies array, and retrieving the results, though it requires the debugging feature to be manually enabled first.
