QuoteWhere's NoScript for Firefox 57 "Quantum"?
2017-11-14: We're working hard to make NoScript for Quantum available to you as soon as possible, definitely by the end of this week.
Please be patient: if you feel naked while you're waiting for the "brand new" NoScript, you can still use the "regular" NoScript 5.x (and all the other extensions of yours) on Firefox 52 ESR, which will receive security updates until June 2018. See you soon!
