[Full-disclosure] Mozilla protocol abuse

[Thor Larholm]

Mozilla is trying to hatch a list together in 
https://bugzilla.mozilla.org/show_bug.cgi?id=389106.

Your mileage will vary not due to the browser but due to your installed 
applications, which is where local file detection vulnerabilities come 
in handy.

Cheers
