Reading Habr mobile a 56K link (the 3G speed is reduced to such a level dialogo if you cannot afford the monthly limit on traffic), often face this problem:
The article is loaded, begin to load the comments, and BAM, the page disappears and instead it shows "The connection was reset".
You have to monitor closely the progress of the download and time manually press Stop.
Maybe you can configure Firefox so that when you lose the connection with the server he used to leave the page as is, and is not discarded and are not replaced its the whole screen of the error? Can there be any option for this in about:config or an extension?
