Save Tab URLs is a Firefox extension designed for users who need to manage their browser tabs efficiently. This subscription-based tool allows users to view, edit, and save the URLs and titles of all open tabs in a current browser window as plain text. Once installed, users can easily access the extension via a toolbar button, ensuring that all required tabs are loaded for optimal functionality. The tool provides features such as copying the list to the clipboard, saving it to a text file, and editing the text directly within the interface.

The extension addresses a common limitation of Firefox, where not all tabs are automatically loaded upon startup. Users must manually reload any absent tabs to save their URLs and titles. The extension does not interfere with the browser's operation and allows for flexibility in managing tab interactions. For users who want to save all present tabs, there is an option to configure Firefox to load multiple tabs on startup, albeit with a potential impact on performance.
