Rated 3 out of 5 stars
I was looking for this when i got tired of 'temporarily allow' in noscript, but found it too simplist.
later i discovered that the same functionality but with more comfort and usability (imagine you just HOVER the mouse over the noscript toolbar button and the menu appears!) can be achieved turning noscript into 'allow scripts globally' while feeling much safer.
in noscript you can also have a blacklist in effect even with "allow scripts globally". sorry to say this, this is not intended as publicity for noscript but a sincere subjective comparation.
