Rated 4 out of 5 stars
Although it has taken a long time for the wounds to heal after the whole NoScript/adblock fiasco, I have come to the conclusion that NoScript is the add-on I most trust with my JS blocking needs.
In terms of usability this is the best add on out there. Although initially there is a sort of training period as you allow JS for the different sites you use, after about a week's use you rarely need to tweak anything else. That the interface has been replicated for other add ons like CookieSafe is quite a testament to be proud of.
The only reason this has received 4 stars rather than 5 is because of the previously mentioned issue with AdBlock. Although neither side came away particularly in the right for their actions, NoScript went too far. Also there was the issue of commercial interest in order to make money from the add on. This might not be related to the add on itself, but certainly relates to the security and anti-corporate reasons one would install something like NoScript in the first place. At least it's not gone in the direction of Ghostery or TACO/Albine!!!
