Google Material Design Resizer
Description from store

Preview your page at different breakpoints (desktop, mobile, tablet) in the new interactive viewer from Google. And without even opening a new tab!

UPDATED TO WORK WITH HTTPS.

It also works with localhost / 127.0.0.1 URLs, perfect when developing locally!

USAGE
Click the button, and an overlay of Google Material Design Resizer (https://material.io/resizer/) with the current URL loaded will be displayed.
Click again to hide the overlay and get back to your website.

REQUIRES HTTPS
The extension now supports HTTPS pages.
Actually, it's more than that: Google Resizer now *requires HTTPS pages*. Using the extension (or directly the Google Resizer website) on an HTTP-only website will make Google Resizer enter an infinite refresh loop.

This is due to Google Resizer forcing the `Upgrade-Insecure-Requests` header (https://developers.google.com/web/fundamentals/security/prevent-mixed-content/fixing-mixed-content#upgrading_insecure_requests), which forces any HTTP resource to be loaded over HTTPS. This directive *cascades to iframes*, meaning that non-HTTPS page will never be loaded by Google Resizer tool.

As most websites are now available over HTTPS, the main issue with that is local development.

To make your local pages available over HTTPS, you can either:
- enable HTTPS on your local server. E.g see the [`https` option in BrowserSync](https://browsersync.io/docs/options#option-https)
- use an SSL proxy like [ngrok](https://ngrok.com/docs#bind-tls).

Doesn't work for developing locally on localhost, get Heads up! popup and page continually reloads. Good for public websites, shame as it would be an amazing development tool.
