The “off” version of “Always show the URL bar” function under “Advanced” in Preferences is a little bit broken. Really cool function but at the moment not completely working, at least for me.
It has a tendency to keep the header text solid, and not allowing access to the URL bar. It can flicker back and forth when moving the mouse over it, but when stopping the mouse or clicking, it will automatically become just text. Can be temporarily fixed by moving the mouse down onto the open tab and back again a couple of times
I am using the newest version of Brave on Windows 10 Home version 1709 on an Acer Aspire btw.
Hope that helps, and have a good day!
