not a popup for everything blocked, but perhaps a little resizable window that the user would bring up with a function in the noscript icon's contextual menu.

Then it would list the URLs of everything blocked. I am not sure if radio buttons or just a copy@paste into a top text entry box would be better though. Though a URL entry at that point might be decent.

Yea, just dump the urls into the window and then the user can copy and paste the ones they want into a box at the top and hit a button there; entering it into the whitelist.

That sounds fairly simple to implement, though I have not seen the noscript code or know what language it is in.

If you have a better idea please tell us.
