Description

  • When I open a ticket on Redmine, JavaScript is broken. See screenshot in attachment. As a consequence, I can’t edit the description of the ticket or add relationships to other tickets.
  • When I visit https://tails.boum.org/install/download I get the no-JS version.
  • When I disable NoScript, JavaScript works again.
  • The happens in 4.0~beta2 and 3.16 on a fresh boot.

If we don’t yet have a test to check that JavaScript works in our releases, I think that we should.

As said in my private email earlier today:

  • I think that’s Bug #17007 (which does not happen every time).
  • If restarting Tor Browser fixes it, then this is definitely a duplicate of Bug #17007. Could you please try that?

  • Subject changed from JavaScript broken in Tor Browser 8.5.5 to JavaScript sometimes broken in Tor Browser 8.5.5

Indeed, it’s not happening every time and restarting Tor Browser fixes it.

I was unlucky enough to face this 3 times in a row: yesterday on bare metal, today on bare metal, and today in a VM. I started the VM again right now and I didn’t face it.

I’ve never faced this issue in the past (and only started 4.0~beta2 very rarely since it was released). Is it possible that this issue has become much more frequent lately?

Thank you, so this is indeed a duplicate.

It happened a lot on Jenkins in the last few months. Unfortunately:

  • I can’t tell whether it also happens on Tails 3.x as we don’t run the corresponding fragile tests there ⇒ no data :/
  • I can’t tell whether it also happened earlier because:
    • We were not running fragile tests anywhere before.
    • Nobody was analyzing test suite results much before I resumed doing so 2 weeks ago.

Which makes it hard to assess how severe the problem is.
Last time we had such a bug it was pretty hard to debug and we were only saved thanks to the Tor Browser folks.

Anyway, see you on Bug #17007 :)
