Tor-hosted NoScript updates
From this release on, NoScript versions for Tor Browser are hosted on Tor’s infrastructure, allowing us to deliver more timely and reliable updates.
Distinguished by a version number ending with « .1984 », they are otherwise equivalent to their AMO (stable) or pre-release counterparts: e.g. 13.5.2.1984 (Tor) = 13.5.2 (AMO).
