How do you know it's crashing? Are there any files in: C:\Users\(username)\AppData\Roaming\Mozilla\MetroFirefox\Profiles\(profile).default\minidumps ?

Then it's not a crash most likely. Can you give a description of what you see happen?

I open it.... I see the logo. then 1.5 seconds later...it crashes and takes be back to the start menu

Could you check a registry key entry for me using regedit.exe? Under HKEY_CURRENT_USER\SOFTWARE\Mozilla\Firefox is there a value there named 'MetroD3DAvailable'?

Yes

https://wiki.mozilla.org/Firefox/Windows_8_Integration#Diagnosing_Startup_Problems I've added a section to the wiki about checking for unsubmitted crash reports. If you wouldn't mind checking to see if you can find them, please do. I'll fill out the remaining logging options when I get some time.
