Simply what you need. Works. It doesn't just resize the viewport, but it emulates the http request of a phone, allowing you to do backend processing.

The functionality is great. My only gripe is that the "Remove advertising" popup advertises $4.90/year and then after you actually create your account it turns out to be $4.90/month. Hopefully it's just an oversight rather than a bait-and-switch but it feels grimy nonetheless.

Cannot rotate and cannot scroll

great app!!!!

Vraiment excellent !

This thing works like a charm. I love it.

the best mobile view switcher I have ever found! Very useful extension for debug or just trying it!

the following "error" appears in the console after installing the extension:
Error: An unexpected error occurred spoofer.js

Perfect, cool layout, awesome UI&UX, does the job in the most perfect way possible. Good job <3

Latest Firefox on Windows 10. Plugin does nothing (dropdown with icons only) and have RAM leakage

Easier to use than the built-in DevTools, but the ads are quite annoying

Merci ! Fonctionne parfaitement sous Brave. Firefox ne permet pas l'accès à l'extension. Utile, pratique et fonctionnelle sur au moins un navigateur. Donc, extension validée et recommandée.

It contains google spyware, aka analytics, I would be using Chrome if I wanted that. It also contains a really annoying advertisement which cannot be dismissed unless you pay the developer. There are better alternatives, for instance, Firefox>More tools>Responsive design mode. To much hassle for some chrome around the web page.

This is really amazing. What a unique way to use a browser on your desktop PC. Functional.

¡Muy bueno... 100% funcional!

Ne fonctionne pas , dommage

Great extension! It would be even better if we could hide safari nav buttons when scrolled to top.
