Comodo vs TrueCrypt

I'm using TrueCrypt file container for portable firefox and some other software that uses internet connection. Alsom i use Comodo Internet Security.

Every time I start, e.g. Firefox, Comodo pops up and asks me if i wish to allow Firefox to connect to internet. I oress OK with "Remeber the answers" checked. But Comodo won't remember my answer and will ask next time when I start Firefox.

I guess it's because every time I mount the TrueCrypt volume, firefix.exe has different hash? Maybe i'm wrong, however, does anyone know how to solve this?

Thanks
