background-color: #e8eefd !important;  /* blue 95% lighter */
 color: #3d3dff !important; /* blue 62% darker */
 /* https://www.w3schools.com/colors/colors_picker.asp */

I found the following css for highlighting all context menu items for Firefox 91 ESR (not working on side-bar items from hamburger menu) /*************************** Highlight context menu items ***************************/ menu[_moz-menuactive="true"], menuitem[_moz-menuactive="true"] { background-color: #e8eefd !important; /* blue 95% lighter */ color: #3d3dff !important; /* blue 62% darker */ /* https://www.w3schools.com/colors/colors_picker.asp */ } How do I apply the same highlighting shown by the red arrow to the text where grey and heavy blue is used for highlighting? I find css very convoluted and it's hard for me to know what ids/parameters to use to get the desired effects. Any help appreciated. https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2021-11-02-08-41-28-04f021.png https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2021-11-02-08-41-46-9a2c8b.png
