Hmmm...  It works for me on both CentOS 7 (Firefox 60.2.1) and Fedora 28 
(Firefox 62.0.3).  

As per the linked documentation - What happens if you SHIFT-CLICK on the 
scroll bar?  On my systems I find that SHIFT-CLICK on the scroll bar produces 
the "warp speed" behavior, exactly as expected.


Back to the original question - I wonder if the chosen GTK theme has something 
to do with the disappearance of the up and down arrows on the scroll bar?  I 
found a note on the Ubuntu forums that implicates the theme.  Testing
