<p dir="auto">My steps to repro:</p>
<ol dir="auto">
<li>Open Firefox 9 on Mac</li>
<li>Go to bootstrap main page (I'm assuming is working off 1.4.0 )</li>
<li>Scrolldown to look at dropdown input element.  Style is broken.</li>
</ol>
<p dir="auto">The select form in chrome is displayed beatifully compared to firefox (at least my version 6.0.2) where you see an "ugly" arrow.</p>
<p dir="auto">I am not sure whether it can be solved or not and it isn't actually a bug.. It also happens in twitter preferences.</p>
