Be careful Block all but whitelist:Through this method, Script Blocker Ultimate will block all scripts but whitelist. Allow all but blacklist:Through this method, Script Blocker Ultimate will allow all scripts but blacklist.

While using blocking Java Scripts, you might encounter some irregular behavior in web pages which can be solved by white listing said web page. I suggest to blacklist News sites that are full of ads and only their texts is important for us.
