Facebook videos won't play using Firefox.

Can anyone solve this? I can't get any videos to play on Facebook when using the Firefox browser, when i click the video it just opens a black screen nothing else, they work on Chrome no problem, i have uninstalled flash player and then re-installed it, also done the same with Firefox and it makes no difference , both Firefox and flash player is up to date and the settings seem to be fine with the the the likes of 3rd party allowed to save information and hardware acceleration enabled on flash player, the plugins are enabled on firefox too!

you can allways try typing into your address bar about:config the black ones are user defined it might be one of them

Could be you need java enabled/installed.

Hi Wizzbang i have Java all up to date so can't be that!

Using google chrome works for me. I can't even see pictures if I go in via firefox.
