Mine didn't show in either window. Try what was suggested in Post 70. Even though it seemed a futile gesture at the time, it worked for me.

#70 doesn't work for me, because I don't use 'themes'.

I use the FF basic design. Tried to update it, thought. No update available.

FF forum has several posts complaining about the disappearing scroll bars.

The only 'solution' offered is: It is a themes problem.

Ok, but I don't do themes. So---it is an FF design problem.
