Say you are browsing reddit.com and opened most of the links from reddit in new tab. Suddenly the network is unreachable. all the tabs go blank without a url in the address bar so later you can't refresh and load those pages allover.
It happens to me often and I think it happens to others too, when a website is not responding you try to open a hyperlink in new tab the loader keeps rolling but nothing happens apart from the status bar showing the url it is waiting for. In that case I can't even copy the url and open in another browser because address bar do not have the url.
If feel this to be a common usability flaw. Does this happen to you? For the record, I use mobile broadband which has a very high network latency and often disconnects when I have low operator signal.

Being a web developer myself I am curious why this happens.
