Google just released Google Chrome 78.0.3904.108 and with it is the return of the ‘Close other tabs’ feature. Google removed the ‘New tab’ and ‘Bookmark all tabs’ options in previous versions of Chrome. Google recommended users drag the tab they want to keep over to the first tab and then right-click on it and select ‘Close tabs to the right’ Google, now that it’s back, don’t touch it again! Back to Mail Online home. Back to the page you came from.
