I can confirm this on a clean TYPO3 4.1.1 installation but don't know what causes this. I could not reproduce scenarios outside TYPO3, e.g. testing with a simple HTML file and selectors. Maybe an JavaScript issue?

I spent some time on this issue:
In typo3/sysext/t3skin/stylesheets/stylesheet_post.css there is a "select:hover" definition, which causes this behaviour. Firefox seems to evaluate this wrong. But I also don't know why we need hover effects on select, input and textarea in t3skin.

"Test" the attached experimental patch which just changes the CSS file.
