 Related source code:

 {{{
   function defaultOptions() {
     return {
       sites:{
         trusted
 }}}

 File

 {{{
 legacy/defaults.js
 }}}

 is similar.

 Under [https://forums.whonix.org/t/noscript-with-security-slider-at-
 safest-permits-around-30-sites/8160 conditions] which are not clear to be
 yet how to reproduce this can lead to white listing these websites in
 noscript even though Tor Browser security slider is set to maximum.

 It's arguable if addons.mozilla.org should be whitelisted by default (I
 won't argue about it) but for sure netflix, paypal, youtube and others
 don't deserve special treatment by Tor Browser. Obvious tracking and
 security risk.

 Looks like pressing the reset button in noscript also results in setting
 these websites to trusted by default in noscript.

 Therefore, please kindly consider to remove that whitelist from noscript.

 Additional suggestions:

 * Have a unit test that greps the source code for (these) websites so
 these aren't reintroduced in later (noscript) add-on versions.
 * Report to upstream (noscript).
