Facebook like button doesn't show in Chrome

I added a Facebook like button to my site, which was generated by the Facebook tool

http://developers.facebook.com/docs/reference/plugins/like/

it works perfectly in FF and IE

But doesn't want to work 开发者_运维问答in Chrome 9

Does anybody know why it happens this way ?

Sorry guys, it was really stupid of me. The cause of this mess is a Facebook Disconnect extension I enabled a few weeks ago - https://chrome.google.com/webstore/detail/ejpepffjfmamnambagiibghpglaidiec

Since it works for you I started exploring my own Chrome. Thanks for your support, you helped me to understand the issue.

FYI - for anyone that finds this, Avast is blocking social media sites by default now with their web plug in! Grrr...
