Firefox freezing with disqus enabled

Hello,

When this plugin is enabled, and i’ll go to my website wereld – nieuws (dot) com the browser is freezing for a minute.

(When you reed a post, not on the homepage)

I was testing my website with disqus disabled, and it was working fine.

I use the theme World Wide.

Best regards,

Justin
