MDN’s new design is in Beta! A sneak peek:

Symbols for are now live:

C:\Program Files\Mozilla Firefox>c:\progra~1\debugg~1\symchk.exe /r c:\progra~1\mozill~1\* /s SRV*c:\symbols\*
SYMCHK: fullsoft.dll         FAILED  - Image is split correctly, but fullsoft.dbg is missing
SYMCHK: qfaservices.dll      FAILED  - qfaservices.pdb mismatched or not found
SYMCHK: talkback.exe         FAILED  - Built without debugging information.
SYMCHK: helper.exe           FAILED  - Built without debugging information.

SYMCHK: FAILED files = 4

C:\Program Files\Mozilla Firefox>

Big shoutout to Mats Palmgren for putting in and Nick Thomas for resolving it.

See the History of this Talk page for what a failed symbol download looks like.

Question: with windbg, if I use a local path like is listed in this example, with a trailing "\", it doesn't work, but removing it works. Is this a typo?

Linux not working ?

I downloaded and it silently failed for my nightly build Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.3a2pre) Gecko/20100218  Minefield/3.7a1pre ID:20100218030721.  It turns out it's getting a 404 File Not Found error retrieving .  I don't know if this is supposed to exist, but I filed bug 547324 about the silent failure.

Symbol server for Windows 64bit builds?

It appears only works with 32bit builds. But we have nightly builds for win64 now.
