I searched quickly and know the older css tricks for tabs on top.. butI opened FF this morning to see the new version. My tabs now show individually at the bottom above my windows toolbar. It only shows the active tab unless I am at the firefox start page. I have to cntrl - tab to see any of the others.

I tried changing themes etc. Currently on system theme. I have 4 tabs open but only show this one at the bottom. I want them all showing at the top as I've seen in screenshots. Pic of mine below showing the 3rd tab only when there are 4 there.
