After the most recent update, Norton detected a threat from this extension. I will not be using this anymore.

Diese Bewertung wurde für eine vorherige Version des Add-ons (0.3.0.1-signed) abgegeben. 

The add-on's complete source code is out there and you can see for yourself whether there is anything malicious.

You should report this to Norton instead of complaining it here.

FYI: here's the result from virscan.org.
