Carol has used Firefox for Android to search for, browse, and save a particular image. A compressed copy of her /data/data/org.mozilla.firefox folder is downloadable <a href="org.mozilla.firefox.tgz">here</a>. What is the serial number of the lens used to take the downloaded picture? Add the full serial number to the end of http://bit.ly/SANS_ to progress forward.

Hint: You may have to use resources outside the org.mozilla.firefox folder to fully answer this question.
