Limit Tabs is a Firefox add-on designed to manage open tabs effectively by enforcing a limit. It automatically removes the newest tab or the least recently used one when the number of open tabs exceeds the specified limit. Users can choose to apply this limit per window or globally, making it a flexible solution for those looking to streamline their browsing experience. Pinned tabs are excluded from this management, ensuring that important tabs remain accessible.

This add-on is particularly beneficial for users who may feel overwhelmed by excessive tabs, such as individuals with autism. Upon installation, the default tab limit matches the current number of tabs across all windows, and users can easily toggle the add-on on or off using the toolbar icon. Additionally, the preferences allow for further customization, enabling users to tailor the functionality to their specific needs.
