Another simple CSS job

NOTE: I will not be paying for this job as it's a 30 second respond from the person who knows what to do, BUT a 10/10 Review/Feedback will be for the first person who sends the right answer. Please take a look at [login to view URL] In IE the menu on the left,looks the way it should, but in firefox it doesn't. Whoever knows what to do, please send the answer to me through PM and at the time that you are bidding on the project, include this: "I understand that I won't be paid for this project and I will only get a 10/10 rating if I manage to send the right information" Thanks in advance
