Firefox is not letting me open another tab when I click the 'new tab' button. It says 'done' in the corner, but never opens a new tab.
Firefox is not letting me open another tab when I click the button or the 'new tab' in file. I have restarted my computer, installed an update, and I still have the same problem browsing.
