For better Web compatibility (and for technical reasons), they will not bubble up when Firefox is in multi-process mode and the <select> element is displayed as a drop-down list. The behavior is unchanged if the <select> is presented inline and it has either the multiple attribute defined or a size attribute set to more than 1. Rather than watching <option> elements for events, you should watch for change events on <select>. See bug 1090602 for details.","When Mozilla introduced dedicated content threads to Firefox (through the Electrolysis, or e10s, project), support for styling <option> elements was removed temporarily. Starting in Firefox 54, you can apply foreground and background colors to <option> elements again, using the color and background-color CSS properties. See bug 910022 for more information.
