I can easily replicate the issue on any system.

1.) Launch Firefox. 2.) Open several tabs of varying content making sure at least 1 is a flash video. 3.) tear off tab that is playing flash video, and send to second screen. 4.) Try to enable full screen playback in the new tab.


If the video is playing, the playback controls will not show up. If you pause it you will get the playback controls but when you enable full screen it will go to the other monitor and then disappear behind the main Firefox instance. (Every once in a while it will stay up front but it's still on the wrong screen) If you reattach the tab into the main Firefox instance it will behave normally again.

Such issues can be a problem with hardware acceleration in Firefox and/or the Flash plugin.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You can check for problems with current Shockwave Flash plugin versions and try this:

  • disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
  • disable hardware acceleration in the Flash plugin
