Issues after macOS Sierra upgrade I recently updated to macOS Sierra on my MacBook Air. I have started noticing that desktop applications will startup automatically.

I have noticed this with Facetime and Slack. Whenever I access Facebook via Google Chrome, Facetime tends to open up and when I access Slack in the browser, the Slack desktop application starts up.

I have checked that I have not set any shortcut keys and it keeps happening frequently. Has anyone else noticed this issue? What can I do to stop it?
Be sure you do not have any OS updates left: Upgrade OS X operating system

Be sure your Google Chrome is up-to-date and check Settings -> Extensions
