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