I'm a huge fan of Firefox extensions; it's high on the list of reasons to never stop using the browser. But there's always a downside, and my paranoid side has found it.
If there were a way to allow Greasemonkey scripts, that would be ideal. However, that requires two independent developers to collaborate and continue to work together as features change or are added, a likelihood that's pretty low.
I'll be getting rid of NoScript; it was an experiment anyway. It's just disappointing to see good ideas step on each other.
