The simulator cannot be activated on this native page of your browser. Try another tab or browse to a site and then relaunch.

Simulator not closing when clicking on the disable simulator button or the toolbar icon

Hi there,
We love the simulator however recently the disable simulator button (available when simulating the phone) and the extension icon (in the toolbar) have not been returning to the non-responsive view.
Thanks!
