Add-on worked at first, but stopped working without warning, exposing my real IP. By all indications, it appeared to be still working and would even appear to connect to the chosen server.

After receiving adds targeted to my real location, I checked my IP, my real IP displayed even though the add-on status indicated connected.

Only after uninstalling and reinstalling add-on did it work as it was supposed too.

I suspect this may have started when the add-on begun going straight to the settings upon opening. That behaviour has now stopped after re-install.
