This didn't happen in earlier versions, but when I go to play a youtube video. It may play or won't. But after I click on the NS icon, no menu appears. Soon as I disabled the addon youtube worked fine.
Using firefox 57
Had to stop using this addon. Using noscript suite lite for now
NS 10.1.5.5 prevents youtube working
