When I try to download and open Firefox with OS 10.6.3 I get an error message saying "A copy of Firefox is already open" -- and it's not.

I have a new MacBook Pro running OS 10.6.3. Every time I download Firefox and try to open it, I get an error message saying, "A copy of Firefox is already open." And it's not.

This happened

Just once or twice

I bought my new computer.

Bonjour, Je ne peux pas ouvrir Firefox. Voici le message que je reçois : " Firefox est déjà en cours d'exécution mais ne répond pas. Pour ouvrir une nouvelle fenêtre, vous devez d'abord arrêter le processus Firefox existant ou redémarrer votre système." Je ne vois pas de processus existant. Si je me sers de copie de documents PDF et qu'il y a des liens dans le document, les liens ne fonctionnent pas.
