Thank you for the reply, I will see if I can find another PC to install it on. In the mean time I don't find an uninstall for the extension, (it's not in the Control Panel Programs and Features) what is the procedure to uninstall it? FYI removing the extension from Chrome and adding it back worked. So now the extension icon is white but it is not prompting me to select a credential, or fill in the credentials or add the credentials to Passwordstate. Can you tell a website that you know works with the extension to test against?
