Tabs have disappeared from the top of the screen (no tab with + sign). I can open a new tab via the file dropdown but then it is the only one I can see and I can't access the previous tab. Effectively there is no tab function at all and opening in safe mode is just the same.

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options) key, and then starting Firefox. Is the problem still there?
Actually, it eventually sorted itself out with a simple refresh. Oddly, it didn't seem to have anything to do with extensions. Thanks anyway
