Menu que se atropela no FF

Boa noite,

Fiz um menu usando <ul> e <li>, vertical (além de um horizontal) para um layout. Assustadoramente, tudo no IE está perfeito, porém, no Firefox, o menu da esquerda, que deveria ser vertical, se atropela, fica uma bagunça... alguém tem idéia do motivo?

Aqui está o layout:

Aqui o CSS:
