Hey,
Sorry for the shameless plug this is will be the only one I promise!
We have made a firefox addon for privacy and security browser called hedgehog! You can sand-box yourself against cyber threats and never be the victim again when you open PDFs or visit links.
You can install flash plugins or anything you might need within your cloud browsing session without compromising your security. Sand-boxing is an effective tool against cyber crime that can easily be explained to anyone.
