Detalla ampliamente la informacion.
eso si, seria bueno una barra para ver constantemente la ip y una banderita para saber de donde es la conecion.

Although this IP finder works, it opens a new tab, showing, essentially, the same information that the icon's pop-up does. In other words, not only is it redundant, it takes up additonal resources, unnecessarily. Since the tab "feature" can't be turned-off, this is no better (and, arguably, worse) than accessing an IP finder on the web. I removed it from my add-ons.

Fonctionne bien et très pratique, compatible multiprocess et webext.

The drop down window is a bit too small for comfort. I think this would be better as a toolbar, and there would be more room to add stuff.
