I have created a standard hover background which, using various stanzas, applies to everything except the toolbar bookmark items and buttons. The following code doesn’t have the desired effect on bookmarks. What will? The browser toolbox only shows the main window so I have improvised.

toolbarbutton.bookmark-item(hover) { background-color: #6495ed !important; }

I can’t think what to use for toolbar buttons such as UBlock Origin.

      Unless I’m missing something, that looks pretty much as it should be. What’s wrong with it?

        Thanks. I tried selecting every category and nothing pointed to the bookmark items. They are all folders and are on the menu bar, as are the toolbar buttons. I did find what seems to be the set of toolbar buttons but the following code has no effect on the hover colour :

        #mainPopupSet { --toolbar-field-focus-background-color: #6495ed !important; }

          I think you should take a screenshot that shows the thing you are trying to change background color of, because currently I have no idea what it might be.

            Thanks. Below is a screenshot of toolbar buttons and bookmarks shown on the menu bar. When I hover over any item, the background colour is a light grey (probably the default).

              In that case the code you posted should work, provided that you fix the hover syntax:

              toolbarbutton.bookmark-item:hover { background-color: #6495ed !important; }

                Thanks. What about the toolbar buttons?

                  You could do this:

                  toolbar .toolbarbutton-1:not([disabled]):hover > :is(.toolbarbutton-icon, .toolbarbutton-text, .toolbarbutton-badge-stack){
  background-color: #6495ed !important;
}

                  But if you want to just change the background-color of all the elements where that same color gets used (so buttons, bookmark-items, tabs scrollbuttons, sidebar switcher button etc.) then it would be much easier to redefine the value for the variable they all use:

                  :root{
  --toolbarbutton-hover-background: #6495ed !important;
}

                    Thanks again. That does not have the desired result on my browser. The following code changes the hover colour of all toolbar buttons including bookmark items.

                    toolbarbutton:hover { background-color: #6495ed !important; }
