v 11.1.5
============================================================
x Updated TLD
x Fixed potential infinite loop via DOMContentLoaded
x Work-around for Firefox 82 media redirection bug (thanks
  ppxxbu and skriptimaahinen)
x Updated TLDs

You can still download NoScript "Classic" (5.1.9) (SHA256) for Palemoon, Seamonkey, Waterfox and possibly other "vintage" (pre-Gecko 57) Firefox forks here: we'll do our best to provide security fixes as long as supporting browser still guarantee their own security updates.

Notice: you may need to open about:config and set your xpinstall.signatures.required preference to false in order to install NoScript 5.x, since Mozilla doesn't support signatures for legacy add-ons anymore. If you're using a non ESR Firefox, you may also need this hack.

  reporting)
