Desktop browser works fine.

Can you provide the crash ID from about:crashes in any other Firefox?

sorry about that. this is cleaner: cd288e7e-3718-42b5-bc8e-82af4bfca435-browser cd288e7e-3718-42b5-bc8e-82af4bfca435

These crash reports haven't been submitted (no *monthday* at the end). Try to click them.

information from copying and pasting weren't formatted well. my previous comment has the actual crash report id. The screen shot has them, along with the date submitted.

The crash report URL is: https://crash-analysis.mozilla.com/hang-reports/2012/11-14/hr-20121114-4a717409-4001-4adb-9be7-c1ea23115c86.html Are you sure it's about your current crash because it's a Flash hang and your home page is about:home with no Flash content. See bug 797116.

It probably is not. I've clicked on nightly for modern many times, but it doesn't produce any new crash reports. I've uninstalled flash and set my homepage to blank as a precaution as well

My guess is that this is related to DirectX. DirectX 10 is required to use Firefox for the modern UI. Eventually, attempting to launch Firefox for modern UI will simply launch desktop Firefox (see bug 807669) but for now it just crashes. Can you verify that DirectX 10 is supported on your VM?

We're working improving report submission to get at startup crash reports.

Some of the steps are a bit hackish, but we do have prelim startup diagnosing steps here - https://wiki.mozilla.org/Firefox/Windows_8_Integration#Diagnosing_Startup_Problems

Please re-open if this still happens for you with today's Nightly build. I think this is a duplicate of bug 844954.

I try Firefox for Metro on Windows 8.1 in VirtualBox 4.3.2. And I have the same problem with comment 0. Please tell me if any information is needed.
