 > The symptom to look out for is JavaScript //not// working on websites
 even though it should be enabled, especially in the default state after
 installation. If you start a fresh browser and don't open the Torbutton
 Security Settings dialog at all, the slider level defaults to Standard, so
 JavaScript should be enabled - but:

 work if you move the slider away from Standard to Safer or Safest, confirm
 with OK, and then move it back to Standard again

 Thanks for the detailed explanation :)

 OK, so in Tails the browser homepage is https://tails.boum.org/home/. It
 does use JavaScript sometimes, and thankfully for the purpose of debugging
 this problem, we're currently in the (rather rare) situation where it does
 run some JS in a way that can trivially be noticed. So I could confirm
 that this piece of JS does run just fine on our homepage when starting Tor
 Browser 8.0a10 in Tails. Then, FWIW, I immediately set the security slider
 to "safest", reloaded the home page, and confirmed that our JS was not run
 this time. So I think the use cases we care about at Tails are not
 affected => no need for an AffectsTails keyword.
