If you have recently tried apt-get uprade, you will notice that mozilla has an uprade. However it errors out with problems upgrading mozilla due to an error in the script that it needs to finish the job. Apt-get -f install and dpkg --configure -a won't fix the error, but editing the /usr/sbin/update-mozilla-chrome script as root will fix it. Look for line 68 and 69 and change the ] to } after the word LIBDIR. Then try apt-get -f install and all will be corrected.

HTH,
