Comment 10 for bug 1725680

@Sebastien
Well, hmmm, it is possible that #1727237 is the same bug. The wifi I was using at that time was a bit weird in regards of having a captive portal: It seemed to me that it was implemented to show a captive portal in principle when connecting to it. But while some other people around were directed to that captive portal everytime they connected to the wifi, I saw it on my devices (Android phone and the laptop where I send this report from) only at the first connection - then I regularily connected to this wifi for months(!) and the captive portal was never shown again to me! And that's the reason why I even forgot to metion it at all in this bug report.
