This is the new chapter of the https://bugzilla.mozilla.org/show_bug.cgi?id=1084606 adventure.

With the latest FF34beta windowsXP, I now have no more specific error message on error: instead I get some generic message: "Connection was broken (La connexion a été interrompue) The connection to 192.168.xx.xx:8080 was broken when loading page The site may be temporarily unvailable or overloaded. Retry later ; If you can't browse any web site, check network connection of your computer ; If your pc/netwrk is firewall/proxy protected, make sure Firefox is allowed to Web" from linux: openssl s_client -connect 192.168.xx.xx:8080 -showcerts < /dev/null CONNECTED(00000003) 140465755293344:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:177: --- no peer certificate available --- No client certificate CA names sent --- SSL handshake has read 0 bytes and written 305 bytes --- New, (NONE), Cipher is (NONE) Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE

As far as I can tell this is the same as Bug 1090765. Bug 1090765 has more relevant information though, so forward duping.
