Future issue with 'window_control_placeholder_support.css' + 'hide_tabs_toolbar.css'
Tested in Firefox developer edition
Hi, I used this two files (window_control_placeholder_support.css + hide_tabs_toolbar.css) for tree-tabs but seems like they will need an update. The window controls only shows when press Alt and the menubar shows behind the urlbar.
I'm not going to update that style combo anymore as Firefox 133 makes us able to do this in a much better way. You'll just need hide_tabs_toolbar_v2.css - no support style required or anything. The old style simply stays as is for ESR 128 users.
Sure, it's possible. But never really an intended feature of hide tabs toolbar, it was just necessary to do it because of how the old style worked. But if you want to have menubar work like that then I think you can use overlay_menubar.css with the v2 hide tabs toolbar.
