Is there a way, via about:config or viable extension/add-on to make a double/dual bookmark toolbar in Quantum 57.0.2? Alternately, can the font size in the toolbar (and ONLY in the toolbar) be reduced?

As the first reply implies, you can use custom style rules to modify the appearance of the Bookmarks Toolbar. To apply the rules, you would create a userChrome.css file.

Thank you both! I will do this tomorrow! I'm not actually using FF33, but PaleMoon. With this tweak, I will be migrating back to FF tomorrow.

Greatly appreciate the input!

Not all info is in one place, Someone will make sooner or later.

Did not provide all the info before due to your Version # displayed.
