Correct, it is no longer there. I have no idea why they took this out. Previously it was there, and it also told you that you could close a tab by pressing "CTRL" + "w" at the same time. That still works, but you have to remember the key combination from versions of Firefox. One way around this is to right-click on the tab and it will give you the option to close the tab - but it doesn't tell you the optional key combination. What I do not like about all this is that I got into the habit of using the pulldown from the Menu - now I have to unlearn that and learn to automatically right click the tab and then choose - this requires me to stop typing and pick up my mouse. I don't want to do this, and I see no reason why Mozilla took away the Close Tab option on the Menu dropdown. Makes no sense to me. Just makes it bothersome. Lucky I remember the key combination.
