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!

UPDATE: Change to 4 stars after response from developer. (Would still like to see some reporting or feedback from the plugin that reports when blocking occurs and what is being blocked.)

The author should explain how to use this extension. Once installed, one can click on the ion which displays a little red badge. Click it again and the little red badge goes away, but there is no indication what is happening or what the little red badge indicates. One star for now because we have no idea how to use or what is happening.

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