To turn off debug output for the CEH, change the registry value from 01 to 00, or delete the CEHDump key.
=== Diagnosing Startup Problems ===
Due to the embedded nature of metro browsers, diagnosing startup problems can be a bit of a pain. There are a few things you can do to help devs figure out what's going wrong.
<b>
1) Launch the metro browser interface on desktop to confirm the install is working.
</b>
* Navigate to firefox's install location in explorer
* Hold shift, right-click the folder with firefox.exe and select open command prompt.
* in the prompt type 'firefox.exe -metrodesktop'
The metro front end should launch in a window on the desktop. If not, try uninstalling and re-installing. If that doesn't help, please file a bug.
<b>
2) Check Direct3D start up check results
</b>
Using regedit.exe, check under the following key for a value named 'MetroD3DAvailable':
HKEY_CURRENT_USER\SOFTWARE\Mozilla\Firefox
If the value is 0, Direct3D startup checks failed. Please file a bug, and post the Graphics section of your desktop browser's about:support section to the bug. If there is no value, please file a bug. If the value is 1, startup checks succeeded.
<b>
3) Check for submitted crashes reports
</b>
To check if metro fx is generating and submitting crash reports open explorer to the following path:
C:\Users\(youraccount)\AppData\Roaming\Mozilla\MetroFirefox\Crash Reports\submitted\
If the folder exists and contains text files please file a bug and copy the contents of a few of the most recent files into the bug.
<b>
4) Check for unsubmitted crashes reports
</b>
Metro firefox can not submit crashes for analysis unless the browser fully starts ({{bug|797023}}).
To check if metro fx is crashing on startup, open explorer to the following path:
C:\Users\(youraccount)\AppData\Roaming\Mozilla\MetroFirefox\Crash Reports\
In this folder look for two files:
LastCrash lastCrashFilename
If both files are present, delete them, and try restarting Metro Firefox again. After doing this, check the folder again. If the files return, a startup crash is likely.
There are two things you can do t this point to help diagnose the problem:
<b>Option 1</b>: Use Desktop Firefox to submit the crash report to Mozilla's crash server -
* open lastCrashFilename with notepad.exe
* copy the temp path and note the file name of the crash report
* open the temp path in explorer and locate the two files associated with the report.
There will be two files, both will have the same file name (a uuid string) and the extensions .dmp and .extra.
* shutdown desktop firefox if it is running
* In explorer, copy both files from their location into the follow folder:
C:\Users\(youraccount)\AppData\Roaming\Mozilla\Firefox\Crash Reports\pending\
* start Desktop Firefox.
* Navigate to 'about:crashes'.
* find the uuid of the report you copied and click on its link
If the link does not resolve to a crash server crash report immediately, wait a few minutes and try again. Once the link resolves, file a bug and copy the report's link into the bug report.
<b>Option 2</b>:
File a bug and contact a dev. who you can share your crash report with. Note crash reports can contain user specific info, do not submit these files to bugzilla as attachments.
