Nightly Fennec 22.0a1 (2013-03-20) Aurora Fennec 21.0a2 (2013-03-20) Firefox Beta 20.0b6 (2013-03-20) Devices: Samsung Galxy SII (Android 4.0.3) Steps to Reproduce: 1. Set the plug-in option to disable 2. Open youtube.com desktop version 3. Play a video. Expected: The video should not be played and the "plugin is needed" message should be displayed. Actual: The "plugin is needed" message is displayed but after that the video start to play automatically. NOTE: Also, using http://www.intel.com/museumofme/mobile/index.htm the video can't be played at all regardless of the plugin state
After further investigation the plugins seems to work correct. Closing this as WFM.
