Google Chrome Login Plugin won't pop-up

I have been trying to use Chrome on OS X 10.8.2. with adblock disabled, but I still can't get "Login with Facebook"/"Login with LinkedIn" plugins work on any website. Tried to disable Adblock, no effect. The window just does not pop up. Any ideas? Thanks in advance.

It was DoNotTrackMe Extension causing it. Problem solved. Topic can be removed.
