The new version was horrible to begin with, but it's been gradually smoothing out. The new interface still feels odd, but I'll let it ride a few weeks and see how it shapes up. For the most part I've been browsing the sites that have existing rules from the old version without issues. Today, however, I logged into Office 365 for a customer and nothing at all would load. The only option in NoScript was for Microsoft.com and it was already allowed. I had to disable the extension to get the website to work in Firefox. I would think this is a pretty high profile site that should not be having those sorts of issues.
