Open Multiple URLs is a Firefox extension designed to enhance browsing efficiency by allowing users to open multiple URLs simultaneously. This tool is particularly useful for users who frequently manage lists of links or need to extract URLs from text sources. It offers a seamless way to streamline the process of opening multiple tabs, saving time and improving productivity.

The extension operates under a subscription-based model and requires specific permissions to function effectively. It needs access to browsing activity to manage tabs, storage for saving user settings, and search functionality for non-URL inputs. Additionally, it supports Firefox Containers, enhancing privacy and organization by allowing users to open URLs in separate contexts.
