I've tried deleting and reinstalling my extensions, they appear on my browser but when I click on them nothing happens other then the icon moves a fraction. For example Lastpass is visible but when I click on it I don't get taken to the lastpass vault or the notification that is currently showing. How do I resolve the issue with the extensions not working. It is not last pass as avast, pinterest and any other extensions I have are not working. It is also the same for both my mac and my macbook pro I'm running Sierra 10.12.2 on my mac and Sierra 10.12.6 on the pro.
