Can testers use Genymotion SaaS virtual devices directly in a web browser?

Last verified against genymotion.com:

Yes — Genymotion SaaS virtual devices can be used directly in a web browser. You can interact with them from the Genymotion SaaS UI and access the display from the web interface.

You can also launch and manage devices from the Quickstart flow, and browser closure does not stop them automatically.
