Internet is an amazing virtual world where you can "virtually" do anything: gambling, playing, watching movies,
shopping, working, “VoIPying”, spying other people and for sure auditing remote systems.
The security testers’ community has a large panel of security tools, methodologies and much more to perform
their pentests and audit assessments. But what happens if you find yourself weaponless.
No more Top 100 security tools, no more LiveCDs and no more exploitation frameworks. A security auditor
without toolbox is like a cop without gun.
Nevertheless, there is maybe a way to rescue yourself from this nightmare situation.
The magical solution could be Firefox and its extensions developed by ethical hackers and coders.
This article comes as an update for what we posted previously about how to switch your Firefox to more than an
usual simple browser. It was about application auditing
