So I have an internal server on Mozilla's VPN. It's hardwired in, and has a static IP address. I have a link shortener [0] pointing to the host name. In Firefox Nightly, 34.0a1 (2014-07-23) and the build from yesterday, I haven't been able to resolve the host name, though I can just fine in stable 30.0 and in other browsers. The internal hostname IT gave [1] me seems to be an alias to another hostname [2] (found by running `host nick.corp.mtv2.mozilla.com`). My /etc/resolv.conf does contain the line `search mtv2.mozilla.com`. Others on nightly also can't see my server. At first, I though maybe someone misconfigured the DNS tables on our VPN, but since it works in other browsers including FF 30.0, and I swore it worked in nightly a few days ago; this leads me to think that this is a regression [0] http://mzl.la/nick [1] nick.corp.mtv2.mozilla.com [2] malta-athens-cairo.corp.mtv2.mozilla.com

Which versions of Firefox are affected by this bug? Did it first show up in Firefox 31?

Just upgraded stable to 31.0 (since it was just released a few days ago). Can't reproduce. Since we just incremented version numbers, I suspect 33.0+ as being affected (though 32 could be as well).

john -can you take a look at this?

Further strange behavior, if I use the shortened link ([0] from description), I get the correct redirect but the aliased host fails to load ([1] from description). Using command+r to reload the tab fails. If I open a new tab and paste in the aliased host [1], it works! Going back to the first tab that failed, if I replace the url with [2] from above or the IP address, it fails to load in that tab. But, I can create a new tab and view them.

Nick, you might be experiencing a similar issue to bug 1041511. I just landed a patch on inbound a few hours ago, and there are try builds available. Can you try one of those to see if it fixes your issue? Thanks!

Marc Schifer also reports that in 30.0+, that if you leave a tab open for a while, then try refreshing it, suddenly it fails.

(In reply to Patrick McManus [:mcmanus] from comment #3) > john -can you take a look at this? I'll wait to hear how Steve's patch performs. I don't have any idea what could cause this off the top of my head.

Thanks for the help, all.
