I have a tablet running Android 4.04. I installed the latest flash player 11.3 from the google play store. It works fine when playing videos from the http://nieuws.vtm.be site with in the default (google) browser delivered with Android. When playing these flash-videos within the firefox beta version, only the audio works. The screen remains black. I tried several videos and had always the same result.

Could you try disabling graphics hardware acceleration? Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.

You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.). Then perform these steps:

  • Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
  • In the Firefox options window click the Advanced tab, then select "General".
  • In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
  • Now, restart Firefox and see if the problems persist.

Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:

Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

Upgrade your graphics drivers to use hardware acceleration and WebGL

In the Android Firefox Beta App I don't see any button from which I can get into the options tab. I only find a settings tab at the top right side, but this one does not show any options for enabling/disabling graphics acceleration. As extra information, the tablet I`m working on, is based on an Allwinner A10 (ARM8 1.2 Ghz + 400 Mhz Mali GPU) microprocessor.

I'm seeing this problem as well 15.0.1 running on Honeycomb 3.2.1.

Flash videos have the option to tap to load the plugin, but after it loads only audio plays and the video stays black.

Under Settings, there doesn't seem to be any option labeled Advanced, nor can I find anything about disable graphics acceleration.
