User Agent: Mozilla/5.0 (Windows NT 6.1; rv:11.0a1) Gecko/20111130 Firefox/11.0a1 Build ID: 20111130031011 Steps to reproduce: Flash allows users to have a video full screen in one monitor while doing other web tasks (i.e. surfing) in another. When doing this with HTML5 video however, fullscreen is lost.

This is intentional. We exit fullscreen upon window "deactivate" (losing app focus) to ensure that a malicious web page can't pretend to be your desktop background. Starting with Firefox 13 (i.e. current nightly builds) you can disable this behaviour by setting the pref full-screen-api.exit-on-deactivate to false.

Thank you for very useful information. With full-screen-api.exit-on-deactivate=false it works exactly as I want.
