Starting with release 45 the Firefox browser ( is actively blocking .onion domains.

You can fix this by editing the Firefox config manually:

  • access the config by typing „about:config“ in the browser address bar and pressing the enter key
  • search for „dotOnion“
  • change the value of „network.dns.blockDotOnion“ from true to false
