User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:33.0) Gecko/20100101 Firefox/33.0 (Beta/Release) Build ID: 20140726004002 Steps to reproduce: After the Update from v32 to v33 in Aurora Channel i have weird problems with "Intranet" Websites. We have a webserver internally at http://192.168.1.112 - In IE and Chrome this works fine, also in FF it was never a problem. With the update from v32 to v33 i have strange problems, Firefox still keep saying "Error: Site not found". 192.168.1.112 is pingable and reachable with IE or Chrome. I tried several different proxy settings in FF, nothing worked. With a private tab in firefox all works fine, also with the current stable version v31 all works fine. Just in the normal mode with my default profile in Aurora i have this problems. I tried also a new profile in Aurora, that also helped and the IP works again. It seems to me that the new update have broken my aurora profile. Anybody can confirm that? Actual results: Intranet IPs and Domains not reachable Expected results: Should work like a charm as always

Update: Also i tested it again with a complete new aurora profile and it did not worked here. Still keep saying "Error: Site not found". I don't have any idea how to fix this.

Thanks for the report! I guess it's bug 1041511. Please reopen if you think it is not duplicate.
