BitListen.com Not Working

[HeroC]

I want to try to use BitListen.com. I am using Firefox Beta v24. When I try to enable blockchain.info or MtGox, it says 'No browser support'. So the I disabled NoScript, DNT+, and ABP on the domain.  But it says it still doesnt work. Then I checked the Console, and say it said 'No websocket Support'. But I know Firefox supports Websocket. I will be willing to give a full list of enabled plugins if needed. I appreciate any help, Thanks!
