I use both chrome and Firefox with NS. I recently noticed a strange and odd behavior: NS seems to block all JS no matter what. Even if I select the option to allow script globally no js is ever executed. Take a look here:

Secondly if I disable that option I am still unable to put some website into the whitelist :

FYI websites that are listed in the whitelist are blocked too...this is the first time this strange behavior happens.
Any ideas? I've tried to create a new clean profile, install NS and import the whitelists...nothing changes
PS: latest version of FF
