I'm using Windows 8 Developer Preview. Nightly builds 20111012 and later just won't start. The process appears in the Task Manager for a few seconds, then disappears, but application window never shows up. Launching Nightly with Shift button doesn't help. Last working Nightly build was 20111011.
The breaking changeset seems to be http://hg.mozilla.org/mozilla-central/rev/e0ae39a3298e. Bug 677797 seems suspiciously.
Windows 8 Developer Preview x64 - the same problem. How can it be solved?
Confirming based on two bugzilla reports and a couple more reports on Mozillazine. Not sure if security is the right component for a non-security bug caused by a security fix, but...
Confirming on Latest UX build and Nightly build
This should be listed as blocker.

I could reproduce this. I will investigate.
Created attachment 567368 [details] [diff] [review] Patch (v1) It seems like Windows 8's LdrLoadDll has been changed to accept more values inside the filePath argument. The cause of the crash is that we're passed a value of 1 with that function the first time when we're trying to load user32.dll, and then we pass that to SearchPathW which causes a crash. This isn't technically a regression from bug 677797 in the sense that on Windows 8, we would still crash without that patch if we're trying to load a DLL which has some of its versions blacklisted. Therefore I think we need to take this patch (well, it's equivalent which would apply on Aurora and Beta) on those branches as well.

Created attachment 567369 [details] [diff] [review] Patch for aurora and beta
Comment on attachment 567368 [details] [diff] [review] Patch (v1) IsBadStringPtr is almost never the value we want to be using. I suggest instead, if we don't actually have documentation or understanding of the problem, to use the check (intptr_t(filePath) < 1024))

If not, the status of this bug will be changed to verified when testing on this branches is done, as well.
Why do we need this on Aurora and Beta? Windows 8 isn't a supported platform for Gecko 8 or 9.

Technically it's not a supported platform for Gecko 10 either! But without this, if there's a DLL on a Windows 8 system which we blacklist, we'll just crash. I think that if we can do something safe to fix that problem (which is what this patch does), we should take it. But I'll leave it to drivers in order to make a decision about this.

---------------------------------[ Triage Comment ]--------------------------------- Windows 8 is pre-release and isn't supported by any shipping version of Firefox, therefore we will not track it explicitly. Of course, the bug is already fixed but if for some reason it becomes unfixed we don't need visibility because of our lack of support (and I bet Asa and Robert Strong's team are all over this).
