Responsive Web Design Tester
Description from store

Test your mobile site on mobile devices.
This extension reflects both the size and the browser of the mobile device.

Quickly preview your responsive website designs at the dimensions they will be seen on popular mobile devices.

RWD tester also uses the correct User-Agent, but it does not render web pages in the same way as the mobile device. It is primarily for developers who want to test how a page responds to different devices.

Supports both external and internal network (localhost).

Includes presets for iOS (iPhone, iPad), Android (Samsung Galaxy, Nexus 7).

Add your own devices if you don´t find anything that suits your needs.

Funktioniert nicht. Geht auch nur bis Iphone 7, dabei gibt es schon das 11 Pro. Wurde also ewig nicht angepasst. Entsprechend zeigt er mir die Landingpages auch nur an wie Chrome selbst. Unbrauchbar

me gusta, ya que es práctica y permite agregar nuevos tamaños de dispositivos móviles a fin de testear si tu web se ajusta a esa medida.

I like this plugin of yours. Is does the job but I found 2 issues for me to uninstall this - 1- Firstly on automatic page reload like in angular, react the webpage reloads likes a desktop webpage. 2- It return the navigator.userAgent to be false like in this case - isMobile = /iPhone|iPad|iPod|Android/i.test(navigator.userAgent); So this plugin is of no use to me. Kindly fix these issues

Not practical at all

Bardzo fajne rozszerzenie, najlepsza jest możliwość dodania własnej grupy urządzeń bądź własnego urządzenia o ustalonej rozdzielczości ekranu wraz z własnym User-Agent. Na prawdę polecam!

Me gustó porque es sencillo, tiene una gran variedad de dimensiones de dispositivos móviles que ya vienen configurados :D eso ahorra tiempo a la hora de elegir uno aunque también da la opción de crear tu propia dimensión. Lo único que no me gustó es que aparece en una nueva ventana y eso no se puede configurar, de ahí en fuera todo bien.

Sometimes it creates extension errors like "This extension failed to modify the request header "User-Agent" of a network request because the modification conflicted with another extension" Apart from this error it is useful at many situations.

Does a great job of viewing the site in the requested window size - however doesn't provide a simulated finger input - only looked at this as sick of pressing F12 and switching between device mode on the inbuilt dev tools of chrome (these dev tools do everything you need though...)
