This is no longer a bug. I'm keeping the gist for historical reasons, as it helped to get it fixed. Make sure to read the edits below.

Edit: this trick stopped working as of Firefox 30 realeased in 2014-06-10. Join the comments section to help finding an alternative, and please upvote the bug on Bugzilla for a definitive fix. If you now have double arrows on Firefox, this might solve your issue.
Don't use any other value of
-moz-appearance as the styles inherited are not customisable.

TL;DR (or, the fix)
none. This will "reset" the styling of the element;
0.01px. This will "push" the text a tiny bit to the right;
''(an empty string). This will change anything that extends beyond the element's width to... nothing - and this includes the infamous arrow!

I was experimenting on custom styling the
<select> elements of a form I was building. One of the things I tried implementing was truncating the text with an ellipsis in case it extended beyond the
<select>'s width. It didn't look consistent through browsers, but I discovered something nice.

As this 2011 bug report states, there is an issue regarding Firefox's
<select> elements: it was supposed to ditch the
<select>'s arrow (like Chrome's implementation) but it simply doesn't. People were raging about the subject all over the internetz.

- Firefox doesn't remove the arrow, it hides it. You will have some white space on the right (same width of the now-hidden arrow);
- Chrome removes the arrow by default with
-webkit-appearance:none;instead of hiding. No white space on the right;
- Chrome doesn't support the
text-overflow:''. No evenly-cut text;
- Your best bet is to set some
padding-rightin order to provide right space for your styled version of the arrow. Just keep in mind that Firefox will take the ghost arrow width into account;
- Turns out that Windows doesn't require the
-moz-appearance: none;declaration at all. Tested on 8;
- Firefox for Android needs the whole
widthof the arrow as
text-indent. It means you need to set it to at least
5px, but take care since Firefox seems to double the
- Zooming out (ctrl mousewheeldown, ctrl -, etc) reveals the default arrow. No big deal;
appearanceattribute is not well supported through browsers, so take this workaround with a grain of salt when developing your crossbrowser solution.
Tested on latest versions of Ubuntu, Windows, Mac and Android.
