Hi guys,

I was plotting some diagrams on monday with kibana 4.6. Today I was starting up my pc again and got the following error:

> TypeError: ytPlayer is undefined ([http://localhost:5601/app/kibana#/discover?\_g=(refreshInterval:(display:Off,pause:!f,value:0),time:(from:now-15m,mode:quick,to:now)](http://localhost:5601/app/kibana#/discover?_g=(refreshInterval:(display:Off,pause:!f,value:0),time:(from:now-15m,mode:quick,to:now)))&\_a=(columns:!(\_source),index:%27mod-_%27,interval:auto,query:(query\_string:(analyze\_wildcard:!t,query:%27_%27)),sort:!(%27@timestamp%27,desc)):9)

Only installed mod so far is timelion. Everything is running on localhost. I use firefox and everything works when I use the private surfing modus. I already tried the clear session button and even whiped my complete browser cache but everytime I visit kibana on localhost in standard browsing I get this message.

Does anyone have an Idea why kibana is failing all of the sudden?

**edit**  
Found the problem. It was actually related to a firefox addon I installed. Youtube Replay which, if turned on, causes kibana fail to load in the browser. The addon isn't actually loaded when I start private browsing, so thats why kibana still worked there.
