That extra spacer/drag space for Vertical tabs mode only appeared in Firefox's UI a couple of updates ago.
Likewise the extra flexible spaces either side of the 'List all tabs' button... easy to miss if not creating a new profile.

MrOtherGuy has promptly fixed this breakage. Many thanks :)
For more details see Commit ddba754... and associated GitHub repo Issue #661 - "floating_findbar_on_top.css" no longer working - the findbar is at the bottom again and barely visible'.
Thank you very much for the reply and pointer to your own updated scrollbars style 'scrollable_menupopups.css'... which I had somehow managed to miss for at least the last 3 years... all whilst recommending your excellent repo's contents to others on numerous occasions!
More information on the recent changes to scrollbar styling in GitHub repo Issue #654 'scrollable_menupopups.css in V154 V155'.
Likely a facet of human nature not to look for alternative solutions to a problem that has already been solved.
Using a capital 'C' in 'userChrome.css' and userContent.css file names is a longstanding convention... but not a requirement.
Edit: CSS userChrome modifications work normally in Firefox on Windows OS' with a small 'c' in the 'userchrome.css' file name... unable to test if this also applies for macOS and Linux installations.
