The old version of NoScript is much easier to edit the whitelist, this new version need to edit the whitelist on the debug box.

This add on does its job but it has one major flaw, in that it will regularly forget its settings, especially if you install FireFox on a new computer and it links back to your older set ups.
It often forgets that I have allowed sites access and blocks things randomly.. It is very frustrating at times. I like it, I will keep using it (for now) but if it keeps forgetting settings and I have to remind it to unblock sites regularly going forward, I am going to drop this.

Works good for new Firefox version. UI made much easier than it was. But reloads a web-page with annoying delay.
