TabCloser is a Firefox extension which allows you to close all the tabs of a specific domain with a few clicks. If you have around 5-6 or more tabs of a domain open and you want to close them all, then instead of closing them manually, you can use this extension to make task a lot faster.

After you install this extension, it will add a context menu option to close all the tabs from the selected domain. Just right click on the tab and choose the option “Close all (hostname) tabs”. It will then ask you for a confirmation message and will then close all the tabs from the selected domain. It is not perfect and might sometime not able to close some deeply nested sub domains.

It is a nice extension to use, when you quickly want to get rid of a number of tabs quickly. It works with the latest version of Firefox also.
