When loaded, I pressed "Windows Key + D," to show the desktop. Actual results: Flash crashed. Expected results: Flash shouldn't have crashed.

ProtectedMode=0 does not help
See also bug 852096. This bug at least has STR. I presume that you don't have Avast antivirus installed, right?
I get the Unresponsive Plugin prompt several times before crashing.
(In reply to Alice0775 White from comment #1) > bp-da5b5335-126a-4fc1-8794-266f72130703 Note that this crash is in firefox.exe with no in-process Flash. Bug 852096 however is in FlashPlayerPlugin_XXX.exe.
FWIW, when repro'ing this (Site mentioned in comment 0) I get a Plugin Hang Report: Firefox version 26.0a1 BuildId: 20130914030203 Plugin: NPSWF32_11_9_900_85.dll https://crash-analysis.mozilla.com/hang-reports/2013/09-15/hr-20130915-8885a2fd-7613-49f1-b175-dd770e1cd4df.html
So per comment 4 and 6 this seems to be Flash being slow to respond, with some setups resulting in a RtlUserThreadStart crash stack? Can the crash in RtlUserThreadStart still be reproduced?
