I cannot open more than 1 Tab per window. The "+" does not work as well as the item "New Tab" from the File drop-down menu. What shall I do ?

I have just removed FireFox and reinstalled it again on my Mac Book PRO. When I open FIreFox I canNOT open more than 1 TAB. I click on the "+"on the top line of the window. It should open another TAB but id does NOT. I click on the File item in the top menu bar. A drop-down menu pops up. I click on "New Tab" and nothing happens. How can I get more than 1 Tab on the same window ? This feature works with Safari ! Thank you so much. Best regards

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options)
key, and then starting Firefox. Is the problem still there?

We have seen reports about a Community Toolbar extension causing this issue with not being able to open a new tab. So if you have such a toolbar then start with disabling it.
