I asked about this code on the other post but it got locked..... the code works but it makes my Menu bar smaller and the grayed texts become white as the background so it shows as blank white spaces anyway to fix the code so that it doesn't change the sizes just the colors? and makes so the grayed areas show up as well? <pre><nowiki>/* Source file https://github.com/MrOtherGuy/firefox-csshacks/tree/master/chrome/tabs_on_bottom.css made available under Mozilla Public License v. 2.0 See the above repository for updates as well as full license text. */ /* Modify to change window drag space width */ /* Use tabs_on_bottom_menubar_on_top_patch.css if you have menubar permanently enabled and want it on top */ /* IMPORTANT */ /* Get window_control_placeholder_support.css Window controls will be all wrong without it.
