Crash Data

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1

Steps to reproduce:

Launch any Flash-enabled web page in Firefox 15, such as youtube.com


Actual results:

Firefox reports that Flash player has crashed.


Expected results:

Flash player plugin should not have crashed and should function normally. This problem is new in Firefox 15, the previous Firefox version 14.0.1 doesn't have this problem.
about:config > Setting dom.ipc.plugins.flash.subprocess.crashreporter.enabled to false will workaround this crash.

Do you have Trusteer Rapport installed? We have a known issue with an old version of Trusteer Rapport which was hooking Firefox functions poorly and caused a Flash crash of this sort.
Component: IPC → Plug-ins
FWIW, this doesn't appear to be a hang, just a crash. Are you actually experiencing a hang?
Yes, this is a crash, not a hang. Summary has been corrected, it may have been a typo.

No, I don't have Trusteer Rapport installed. Searching for Trusteer Rapport in All Programs and Firefox > Add-ons Manager returned no match.
Does it happen in Safe Mode (see https://support.mozilla.org/kb/troubleshoot-firefox-issues-using-safe-mode)?

If you disable Flash HW acceleration (see https://support.mozilla.org/kb/flash-video-wont-play-full-screen#w_disable-flash-hardware-acceleration), does it still happen?
If you temporarily disable your antivirus/firewall, does it still happen?
Still happens with Flash player HW acceleration disabled.

With McAfee On-Access Scan disabled, Firefox does not report Flash player crashing, but it seems to be starting/shutting down/restarting Flash player every second. As a result, the Flash content area remains blank during this repeated sequence.
Did you set previously (before the update to Firefox 15) dom.ipc.plugins.enabled to false?
Try to completely disable McAfee for the test.
My setting for dom.ipc.plugins.enabled has always been the default (true) before and after the Firefox 15 update.

With McAfee disabled completely (all the following tasks in VirusScan Console), Firefox now reports Flash player has crashed.
* Disabled Access Protection
* Disabled On-Delivery Email Scanner
* Disabled On-Access Scanner
Still the same behavior after uninstalling/reinstalling Flash player.

There's third-party software that always runs on your computer that causes that. You must find out which one.
After further investigation, we have determined that this is not a Firefox issue and can be closed as resolved.
