Hi, unfortunately this report is not very useful because it does not describe the problem well. If you have time and can still reproduce the problem, please read https://developer.mozilla.org/en/Bug_writing_guidelines and add a more useful description to this report by providing *exact* steps to reproduce (e.g. example website address).

Open up youtube, play videos, and then the ui will freeze. This is completely reproducible across multiple machines with firefox.

> Open up youtube, play videos

How many? Rather 2 or rather 30?

, and then the ui will freeze.

Which exact Flash version is this?

Asking as this is coming to my mind:

2 or more will cause freezing if they are 1080p. Flash is v11.

Comment 5

[Andre Klapper]

Please provide the exact Flash version (by entering "about:plugins" in the address/location bar ).

When Firefox hangs, does it return after a while? If so, does it say that Flash crashed? Can you please provide those crash report IDs?

Gabriela, please put all incoming plugin bugs into Core: Plug-ins. I will move them to the plugin vendor component when I'm sure that the bug is not a Mozilla bug and that we aren't going to work around it.

It hangs for up to 10 seconds, possibly more if flash happens to crash at the same time.
 Where do I get the crash report IDs from?

Please check if the issue occurs using Firefox in safe mode (with your addons disabled):

Or on a new, empty profile:

"Linux

Note that for most distros the package you need to get symbols for will be something like "xulrunner", not "firefox"."

ask your distro

Until there is a stacktrace, this is incomplete.

Depending on your distro, in order to get symbols you may need to:
1. find and enable some repository "for debugging"
2. get the "debuginfo" (or similar) package for firefox or xulrunner (or both).

Details vary from distro to distro.
