Hi All OK so I got a new laptop last night it's running Win 11 on it and I reinstalled Firefox version 104.02 (64 bit). I then copied over my old Firefox's Chrome folder with userchrome.css in it that was working fine on the old Firefox to drop the tabs to bottom. Oddly though it is not working in the new install. Below is the code I have from the old laptop. What adjustments might be needed to drop the tabs to the bottom? I also have some color customization's to color the folders tanish but that too is not working Thanks Dave <pre><nowiki>@import url(userChrome-color_bookmark_folders_Proton89.css); /* 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.
