Description Garrett Holmstrom 2014-03-25 21:12:36 UTC

Description of problem:
When I load a page like YouTube's front page that contains interactive flash content, the UI seems to become unresponsive for a minute or more as it seems to wait for something javascript-related.  Meanwhile, the plugin-container process has since exited and continues to wait in a zombified state for something to call wait on it.  See below for a backtrace from the main thread.  The other threads' don't appear to contain much of interest, but I can add those if it would help.

I reproduced this with both gnash-plugin and flash-plugin.  Disabling it seems to make everything apart from flash content work correctly.

Sorry for the terrible summary/description; I more-or-less guessed as to potential causes and what info might useful.  If you need more info from me feel free to ask.


Version-Release number of selected component (if applicable):
firefox-28.0-3.fc20.x86_64
flash-plugin-11.2.202.346-release.x86_64
gnash-plugin-0.8.10-11.fc20.x86_64


How reproducible:
Frequently, but not immediately


Steps to Reproduce:
1.  Install firefox and gnash-plugin
2.  Wipe ~/.adobe and ~/.mozilla
3.  Start firefox
4.  Navigate to http://www.youtube.com/


Actual results:
The UI becomes unresponsive soon after loading that page.  The following is a stack trace from the main thread in that state:

Comment 1 Martin Stransky 2014-05-20 14:31:44 UTC

Hm, the backtrace is from plugin-container launch. It just executes the plugin-container with plugin itself and waits until is launched.

No idea what can cause the launch delay. Do you see any difference if you set "dom.ipc.plugins.enabled" to "false" in about:config?

Can you also try a new, fresh profile with flash plugin only and without any extension?

Comment 2 Garrett Holmstrom 2014-12-10 21:56:31 UTC

I haven't been able to reproduce this lately, so let's go ahead and close this for now.
