Web App Maker is a Firefox extension designed to enhance user experience by allowing users to create shortcuts to their favorite websites, making them feel like Progressive Web Apps (PWAs). The extension provides two main functionalities: the ability to pop out the current tab and to copy a web app link. This link format, which follows the structure moz-extension://[uuid]/app/[site_to_open], enables easy access to sites like Spotify and Element directly from the browser.

The tool operates on a subscription-based model, catering to users looking to personalize their web navigation. It is important to note that the created links are unique to each instance of the extension and will not function if the extension is uninstalled. Reinstallation does not restore previous links, emphasizing the need for careful management of the extension for optimal use.
