I happened to use Firefox in a part of my appartment that has bad wifi reception, and my test iPhone being my wife's previous iPhone, it doesn't have a SIM, so no mobile network when there is no wifi. Technically, that should be equivalent to being somewhere where any network reception fails for some reason, or where the reception is not stable (which, in fact, was my case. I did get wifi once in a while). Anyways, the resulting experience is that: - since the UI is fullscreen, I had no immediate visual clue that my networking was bad (not a problem, if the following points are addressed) - tapping a link becomes ineffective. That is, nothing happens. The page stays on its current state. Combined with bug 1155132, I was thinking I wasn't tapping correctly (which also happens in some cases where the text is too small) - opening a link in a new tab opens a new tab, with no url. You can't reload when your network has come back, so whatever you opened in a new tab is lost and you have to start over.
Do the new error pages solve this issue?
Yes. "The internet connection appears to be offline"
