Attachment: screenshot

steps to reproduce:
1. Turn wifi ON
2. While the wifi is still connecting, launch marketplace app

expected behavior:
marketplace app offline page loads or we show the loading screen

observed behavior:
The browser "Server not Found" error. Looks like Navigator.online is providing inaccurate info to the app.


See screenshot.

`navigator.onLine` is being reported as `true` when the wifi is enabled but a network connection cannot be established. This is also the case on desktop Firefox (see bug 654579).

Autodetection of a stable network connection would rely on connecting to a determined stable site (e.g., google.com) first to check if we truly have Internet connectivity. I can't think of another way around this, but I welcome ideas.

"offline" in this sense means that there is no chance of connectivity - which on most operating systems will be when there is no available (non-loopback) network interface that is UP.

Firefox does not detect and cannot reliably detect what you can and cannot reach over said network interfaces so that does not effect the online/offline status.

A captive portal detector as per bug 1048131 would however be able to detect this case as not able to reach the open internet.

So, I claim this bug report is not a bug but states that things work as intended.
