Hi Philipp, I've cleared the cache & cookies but I still can't attach anything to an e-mail.
You can check if your plugins are up-to-date.
Your System Detail list shows an older Shockwave Flash 11.8 r800 version. You can find the latest Flash player versions for Firefox on this page:
It is possible that security (Anti-Virus, firewall) is causing problems. Try to disable security software temporarily to see if that makes a difference.
