Misinderstanding in the instructions?? and javascript error Bewertet mit 3 von 5 Sternen

The instructions say that "Signal strength is in dBm so the lower the better it is". My experience is that the best signal strength seems to be from networks with a higher value. Am I misinterpreting?

Causes JavaScript error: 2147500037 on start-up. Disabling this one add-on prevents the error.

Edit: I'm using an ethernet connection alternatively with wireless - because of local wireless inefficiencies. The JavaScript error seems, although I haven't tested it exhaustively, to occur when Firefox is started with wireless disconnected.
