Chrome: The Google Chrome UI for auto-complete request varies, depending on whether autocomplete is set to off on <input> elements as well as their form. Specifically, when a form has autocomplete set to off and its <input> element's autocomplete attribute is not set, then if the user asks for autofill suggestions for the <input> element, Chrome might display a message saying 'autocomplete has been disabled for this form.' On the other hand, if both the form and the input element have autocomplete set to off, the browser will not display that message. For this reason, you should set autocomplete to off for each <input> that has custom auto-completion.Chrome Android: The Chrome Android UI for auto-complete request varies, depending on whether autocomplete is set to off on <input> elements as well as their form.

Firefox: Before 77, Firefox didn't display the value of the label attribute as option text if element's content was empty. See bug 40545.Firefox: Historically, Firefox has allowed keyboard and mouse events to bubble up from the <option> element to the parent <select> element, although this behavior is inconsistent across many browsers. 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.Firefox: 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. Note that this is still disabled in Linux due to lack of contrast (see bug 1338283 for progress on this).Firefox for Android: Before 77, Firefox didn't display the value of the label attribute as option text if element's content was empty. See bug 40545.
