Google Chrome: Tabs only close after two attempts

Since few days, I realized that it is taking "command+w" press twice to close a google chrome browser tab.

This is for sure some extensions issue. I had SlideShow extension creating this problem. If you have this extension enabled, just disable and try out. Otherwise there would be some other extensions creating this problem. Troubleshoot by disabling all of them and enabling them one by one.

In some cases this could be Chrome build problem as well because of flash.
