Hi, I can't change the default hover color of buttons in the navigation bar. It either remains totally unaffected or there appears a larger background image of my color overlaid with the smaller default hover image. Hover on the bookmarks toolbar works fine, except for the "Show more bookmarks" chevron, which behaves exactly like a navigation bar button. I tried these: #nav-bar toolbarbutton:hover, #nav-bar toolbarbutton:hover:active, #nav-bar toolbarbutton-icon:hover, #nav-bar .toolbarbutton-icon:hover, #nav-bar.browser-toolbar hbox#nav-bar-customization-target.customization-target toolbarbutton:hover, #nav-bar toolbarbutton[open="true"], #nav-bar toolbarbutton[checked="true"], #nav-bar toolbarbutton[buttonover="true"]
