Chrome and Javascript question

I have set up chrome to block Javascript globally with the exceptions https, .com .gr .edu .gov .eu After installing latest SpywareBlaster new entries found in Javascript exceptions for example snap.com blocked.
After that I made a test I blocked manually dailymotion.com and then load a site with .gr domain with a dailymotion video and found out that video was playing fine without any problem. So whats the point of blocking javascripts domains as they play along in a white domain site? My only answer is that you are more safe from possible redirects to these sites, but nothing else. Am I doing something wrong or what?

 

If you allow Javascript in A, then any scripts from it will be allowed. The content itself is from B, but the scripts are in A.

The technique you're using, which I mentioned sometime ago, is fine if you somehow are redirected to, let's say a *.cn domain. But, nothing more than that.

If you want more control, then install the extension ScriptSafe. Don't rely solely in the top level domain whitelisting.
