Toybox allows you to simulate and log bugs on your site with different device resolutions. This allows you to quickly see how your site responds to breakpoints and create new Tasks when there are issues.
Testing responsive device resolutions
Launch the Toybox Extension or Snippet on your web page
Click the "Devices" button in the Toybox Toolbar
Select a Device from the Dropdown
Toybox will open a new window in the exact resolution of the Device you selected
Use the Toybox Toolbar on the bottom of the window to create new Tasks at that new resolution
