EDIT: Resolved after reading https://github.com/MrOtherGuy/firefox-csshacks/issues/467#issuecomment-2508813251, but I guess I'll keep this issue for posterity. Can this be documented either in the readme or hide_tabs_toolbar.css + windows_control_placeholder_support.css?

. . . Similar but different compared to #474 I did not touch widget.windows.mica (so it is false). And I use v1, not hide_tabs_toolbar_v2.css

my userChrome.css(git pull'd 10 minutes ago):

@import url(chrome/window_control_placeholder_support.css);
@import url(chrome/hide_tabs_toolbar.css);

Nothing happens when I click on the empty space where the maximize, minimize and close buttons used to be

As mentioned in #474 when I set sidebar.revamp and sidebar.verticalTabs to true I see this: The buttons on the left change on hover and are functional The buttons on the right do not change on hover, and they are not functional

I'm on Windows 11 using Firefox 133 Would it be useful to share my prefs.js? or any thing else?
