 hey all,

 tor browser version 8.5.5 in tails os, navigator object leaks OS,

 you need to modify these
 {{{
  navigator.userAgent
  navigator.appVersion
  navigator.buildID
  navigator.osCPU
  navigator.platform
 }}}
 here's the ticket (with pics), they redirected me to you:

 https://redmine.tails.boum.org/code/issues/16999
 (look at the pics i uploded there)

 i've read the other tickets here, about fingerprinting, point is, that,
 automated scripts will vector attacks based on platform, so this is just
 opening an attack vector

 cheers!
