Actual results:

Flash stopped - rest of browser continued as normal. Could not recover with a page refresh - end up with processes that won't die.

Works fine for me on Ubuntu 12.04 - 32bit.

Could you please try to reproduce this in safe mode?

Yes, I'm seeing the same in safe mode. Here is some extra information. When the flash is running there are two processes showing on my machine:
bird      5406     1 28 11:22 ?        00:00:45 /usr/lib/firefox-trunk/firefox-trunk
bird      5488  5406 24 11:22 ?        00:00:26 /usr/lib/firefox-trunk/plugin-container /usr/lib/flashplugin-installer/ -greomni /usr/lib/firefox-trunk/omni.ja 5406 plugin

When I normally close, first 5488 will close and then 5406. Once I click PopOut apparently 5488 hangs because it doesn't close and leaves the two processes hanging around in the background.

I don't know if this helps, but when I do the same process on my standard Firefox (15.0.1), I see the following processes:
bird      5760     1 35 11:25 ?        00:00:26 /usr/lib/firefox/firefox
bird      5831  5760 69 11:25 ?        00:00:44 /usr/lib/firefox/plugin-container /usr/lib/flashplugin-installer/ -greomni /usr/lib/firefox/omni.ja 5760 true plugin

Notice the extra "true" at the end of the line in between the pid and "plugin" - hope this helps....

Hi, Some more information on this...

I am having the same problem with google chat, which also has a pop-out option. Again, I can see the difference between the process lines between 15.0.1 and nightly build is the missing "true"

Firefox 15.0.1:
bird      6646  5760  0 11:39 ?        00:00:00 /usr/lib/firefox/plugin-container /opt/google/talkplugin/ -greomni /usr/lib/firefox/omni.ja 5760 true plugin

Firefox nightly:
bird      6586  6544  0 11:38 ?        00:00:00 /usr/lib/firefox-trunk/plugin-container /opt/google/talkplugin/ -greomni /usr/lib/firefox-trunk/omni.ja 6544 plugin
