I've read the previous thread about this topic, but I am still encountering issues on OSX. Every time I attempt to use the Chrome extension I am directed to a new tab. Have tried turning off all extensions but Enpass, reinstalling the extension, reinstalling the Desktop client.
macOS Sierra 10.12.4
Chrome Version 59.0.3071.29 (Official Build) beta (64-bit)
