Allow Cloudfront Globally on NoScript
Add these addresses to the Noscript whitelist to allow CloudFront scripts globally:
cloudfront.net
amazonaws.com
While the answer by @samadadi is correct and will allow you to universally accept content from cloudfront, you might want to consider why you're running No Script in the first place.
Cloud Front is a Content Delivery Network that anyone can use, even "the bad guys". If you allow JavaScript downloaded from there to be run, then you are circumventing the protection NoScript offers. If you want to remain safe, I would recommend staying with allowing it on a site by site basis.
This might be an unpopular option because, yes, it is more work, but you will be safer.
Update (just to save people reading the comments below): CloudFront sub domains, while looking random, remain the same between visits. Permanently allowing cloudfront subdomains from sites you trust should be safe, and will only ask you once.
