I did come across something similar showing in my location bar when I tried that site, but I did get videos playing. I am hampered because I do not understand the language of the site. The site does contain adverts and I am not certain if it may attempt to modify Firefox or install software. Note you my need to click the ''lego block'' style, icon at the left of your location bar. Possibly you have adblocking, script blocking, or other security software interfering with the operation of the site. Take care though as such blockers my help you stay safe. Check that your Flashplayer is working ok. *Try http://www.adobe.com/software/flash/about/ * see also [[Flash Plugin - Keep it up to date and troubleshoot problems]] If it is a problem with just that site try to ask on the sites support page or on some other forum.
