Parfait

Tested, works on the 90% or regular web, no issues I could provoke, will replace my other auto referrer app that wasnt updated for long. Dunno if the feature is better or worse for my application in terms of security, but to have some old addon with the many changes in FF over the years, I felt like giving a new dev a try :) thanks dev!

Does exactly what it says it does.
Simple and efficient.
