thought l would ask a new question, though in part this relates to recent changes and a fix in another thread. Namely having tabs below the bookmarks toolbar. long story short there is about a tabs worth of space below my tabs as shown by the attached image, now l have tried tweaking the settings but about all lve managed to do is resize the tabs without touching the space below it and mess up other menus (though lve reset those changes), below lve pasted a copy of my userchrome file in the hopes l can get rid of the space (l did find another topic on the subject [[here|https://support.mozilla.org/en-US/questions/1276985]] but l didnt want to mess anything up by editing something l have little knowledge of). <blockquote> /* 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.
