Tab Control Center di Robin Lieb

Tab Control Center is a browser extension that adds the functionality to Firefox to set a limit of allowed open tabs.

When the limit is reached the extension closes automatically the newly created tap or the most left tab based on your setting. Additionally it shows the number of the current open tabs in the menu icon. Tab Control Center was build to focus on the important things in your browser and to regain back the control of your browser tabs.

Features:
- Set limit of allowed open tabs.
- Show badge which contains the number of current open tabs.
- Option to apply the setting for all windows or per window.
- Option to specify if the new created tab or the most left tab should be closed when limit is reached.
