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 notes by the end of the post.

How to remove hide the select arrow in Firefox using -moz-appearance:none;

TL;DR (or, the fix)

1. Set -moz-appearance to none. This will "reset" the styling of the element;
2. Set text-indent to 0.01px. This will "push" the text a tiny bit^[1] to the right;
