Close All Tabs Extension
The Close All Tabs is a small extension for Googler Chrome and Mozilla Firefox users. Using this extension, you can quickly close all open tabs in all open windows at once except the current tab. Install it for Chrome and Firefox.
How to use?
After installation, you would notice its icon on the browser toolbar. Hit this button whenever you want to close all tabs, and within a second, it would clear all open tabs in all open windows, except your current tab.
Apart from the toolbar button, this extension also offers a keyboard shortcut command Alt + W – which makes it much easier to use. Just to remind you here, keyboard command CTRL + W closes the current tab in Chrome.
Incognito Tabs and Windows?
The Firefox version of this extension closes incognito (private) windows and tabs along with the regular windows and tabs. But, in Chrome, the extension closes only the non-incognito windows and tabs by default.
If you want to close incognito windows and tabs with this extension on Chrome, you need to allow this extension to run in incognito from the Extensions page, as shown in the following screenshot:
Once you enable this extension for Incognito, it would start working in incognito mode and close all incognito tabs and windows along with the normal non-incognito tabs and windows.
