Error checking tends to be optional in shell scripts, but something 
nasty might happen if you had an ordinary file in /home.  The cd would 
fail and you'd proceed to remove everything in and under your current 
directory...
I'd recommend a change to:
cd /home/${x}/.mozilla/firefox/*.default/Cache && rm -Rf *
which means only execute the rm if the cd succeeds instead of doing it 
unconditionally on the following line.

I'm not always this pedantic - just when 'rm *' is involved...
