In order to get FF32 and Flash working I had to manually install Flash by copying the files to the plguins dir. Then using synaptic32 I installed libXmu-dev.
Now I'm having a problem where I can't close any TABS in FF. If I hit the red X, use right-click // close-tab it just won't close. I can open new ones though. It works in the 64bit FF but not the chroot 32bit. It also reports no errors in the console.
