Doesn't save per-site permissions now.

Used to work great, but now loses the site configurations (trusted or not) after every session.

Very powerful app. I was kinda confusing to use at first, but I love being able to block cross site scripting from malware websites and Facebook.

This app would get 5 star from me if all of my settings would sync with my Firefox account.

I have utilized this add on for a long time. Over the last year or so I have been unable to save any settings and have to reset my preferences on a per page basis on each visit. This is very time consuming and is pushing me to find alternate solutions to manage scripts. The forums are no help. Be great if someone could find a solution...

Something funky is going on with NoScript as of late. It has become very unstable in a sense that I click "temporarily allow" but nothing happens. I can see several JS domains to be allowed but none of them is getting allowed. I click on each to allow temporarily but nothing happens: the page neither refreshes nor loads after I refresh it manually. It is happening on a growing number of sites. And just to see the site I end up disabling it globally which totally defeats the purpose of this addon.
