951424 - Adobe Flash Crashes if Firefox is closed while video is running in full screen mode

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Plug-ins, defect, P3)

Description

[Sandeep Kalra]

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:25.0) Gecko/20100101 Firefox/25.0 (Beta/Release)
Build ID: 20131112160018

Steps to reproduce:

1. Start any Youtube Video.
2. Click to go in Full Screen mode.
3. Notice that Flash player runs detached from firefox. The firefox has no video in it.
4. Click to close the firefox (but not the flash player). PS:- I have dual monitor, so, my full screen video is on some other screen, and I can still access firefox on other monitor.
5. Video hangs rather than closing, and adobe error is reported after few seconds.

This bug does not appear on IE9+.


Actual results:

Adobe Crashes.


Expected results:

Video must close along with Firefox.

Perhaps related: bug 675645, bug 634830.

Can you please check about:crashes and submit the crash reports and then past the crash report IDs here?

sjw, please triage plugin bugs to Core:Plug-Ins first, and I'll move them to the Plugins product if we've verified that the fix must come from the plugin vendor.

My about:crashes took me to Mozilla Crash Report with

Thanks

That is bp-8d13cac6-fb6f-4e3b-8f71-8af012131218 (including the bp- part makes Bugzilla automatically link it to the report).

From the stack this looks like it's just Flash taking too much time on plugin shutdown (in NPP_Destroy()).

Looks related to bug 789379 so making it block FWIW.
