Installed and konfigured, but it does not sync. It also interferes with the display of various websites.

Excellent extension, functional on Firefox Mac at home, very practical for monitoring my 130 websites.

I was looking forward to using this extension but it just plain doesn't work. The Chrome version running on the same computer at the same time with the exact same settings runs & connects fine. The FireFox version doesn't do anything...no error messages, no help, no connection, no nothing.

Not ready for prime time. I look forward to when it will be, but this ain't it.
