I recently got norice that Firefox needed updating so I clicked on ok. When it got done updating, Firefox opened with my tabs but the tab spacing was gone as as well as there was no color in the Title bar and menu area, which was normally light blue to match Windows 10 22H2 backbrond I have. I looked at enabling the legacy support in about:config but it was already enabled. I use a Chrome UserChrome.css file that allows the tabs to have just a bit of space between them and rounded edges. I have vision issues and this made it so I could see open tabs and distinguish them. This is the userChrome.css file I used: .titlebar-color{ color: AccentColorText !important; background-color: AccentColor; } .tab-background{ border-radius: 8px 5px !important; margin-bottom: 2px !important; margin-top: 1px !important; } /* NEWTAB button */ #new-tab-button, #tabs-newtab-button { fill: red !important; background-color: rgba(255,255,255,.7) !important; } /* NEWTAB button - hover */ #new-tab-button:hover, #tabs-newtab-button:hover { fill: white !important; background-color: rgba(255,0,0,.7) !important; } .tabbrowser-tab:not([selected=true]):not([multiselected=true]) .tab-background{ background-color: color-mix(in srgb, currentColor 25%, transparent); } menupopup > menu, menupopup > menuitem{ padding-block: 2px !important; min-height: 0px !important; } :root{ --arrowpanel-menuitem-padding: 2px !important; } I attached Firefox with white colored Title bar and Waterfox with colored title bar for example. Is there some setting in the about:config I am missing that was changed from 132 to 133 version? Thank you very much Vernon
