To workaround Bug #17121 (aka. https://trac.torproject.org/projects/tor/ticket/32019) we had to disable Tor Browser’s “Quantum bar”: commit:dfeaa6e96e767dcd96304cceeb5aaa39ef2b4469.

Sooner or later, Mozilla will remove support for the obsolete thing we’ve reverted to, so we need a real fix at some point.

  • No trace of Bug #17121 being back so far, but I’ll want to run the test suite on our slower isotesters (lizard) a few more times to confirm.
  • I can save the current page as “index.html” to the persistent Tor Browser directory (fragile: Bug #15336) failed on lizard
    • The video looks OK except the download down-arrow icon in the toolbar has an orange dot; I don’t know what that means; note that the test suite opened the 2nd page, that we want to save, before the homepage was fully loaded
    • It may be a one-off robustness issue, let’s see what the next few test suite runs say.
