This add-on is far less destructive than NoScript which I found more of a hassle than a blessing, this is a good compromise which will allow you blacklist sites that you know to contain irritating JavaScript (i.e. image hosting sites that try and force pop-ups on you when you click).

Unfortunately the implementation isn't great, the status bar icon only lets you toggle the plug-in on or off for this page, with no option to bring up the list of blacklisted sites or see what sites scripts are running from on this page and block them. The filter also does not support sub domains or wildcards, requiring a rule for x.com and www.x.com etc. and only allows you to block entire domains rather than x.com/adscripts/.

A good idea and room for improvement. JavaScript in FireFox isn't insecure, Mozilla patches any vulnerabilities and it runs with very limited permission. NoScript is overkill.
