Emulate and test other browsers

Your job does not end with ensuring your site runs great across Microsoft Edge and Android. Even though Device Mode is able to simulate a range of other devices like iPhones, we encourage you to check out solutions for emulation provided by other browsers.


  • When you do not have a particular device, or want to do a spot check on something, the best option is to emulate the device right inside your browser.
  • Device emulators and simulators enable you to mimic your development site on a range of devices from your workstation.
  • Cloud-based emulators enable you to automate unit tests for your site across different platforms.

Browser emulators

Browser emulators are great for testing the responsiveness of a site, but each does not emulate differences in API, CSS support, and certain behaviors that you see on a mobile browser. Test your site on browsers running on real devices to be certain everything behaves as expected.

Firefox Responsive Design View

Firefox has a responsive design view that encourages you to stop thinking in terms of specific devices and instead explore how your design changes at common screen sizes or your own size by dragging the edges.

EdgeHTML emulation

To emulate Windows Phones, use the Microsoft Edge (EdgeHTML) built-in emulation.

Use IE 11 Emulation to simulate how your page may look in older versions of Internet Explorer.

Device emulators and simulators

Device simulators and emulators simulate not just the browser environment but the entire device. Each are useful to test things that require OS integration, for example form input with virtual keyboards.

Android emulator

At the moment, there is no way to install Microsoft Edge on an Android emulator. However, you may use the Android Browser, the Chromium Content Shell, and Firefox for Android which we review later in this guide. Chromium Content Shell runs the same Chromium rendering engine as Microsoft Edge, but comes without any of the browser specific features.

The Android emulator comes with the Android SDK which you need to download as part of Android Studio. Then follow the instructions to set up a virtual device and start the emulator.
Once your emulator is booted, click on the Browser icon, and test your site on the old Stock Browser for Android.

Chromium content shell on Android

To install the Chromium Content Shell for Android, leave your emulator running and run the following command.

git clone https://github.com/PaulKinlan/chromium-android-installer.git
chmod u+x ./chromium-android-installer/*.sh

Now you are able to test your site with the Chromium Content Shell.

Firefox on Android

Similar to the Chromium Content Shell, you are able to get an APK to install Firefox onto the emulator.

Download the correct .apk file.

To install the file onto an open emulator or connected Android device, run the following command.

adb install <path_to_APK>/fennec-XX.X.XX.android-arm.apk

iOS simulator

The iOS simulator for Mac OS X comes with Xcode, which you install from the App Store.

When you are done, learn how to work with the simulator through Apple Developer documentation.


To avoid having to open Xcode every time you want to use the iOS Simulator, open it, then right-click the iOS Simulator icon in your dock and choose Keep in Dock. Now just click this icon whenever you need it.

Microsoft Edge (EdgeHTML)

Modern IE VM

Microsoft Edge (EdgeHTML) Virtual Machines (VMs) enable you to access different versions of EdgeHTML and IE on your computer via VirtualBox (or VMWare). Choose a virtual machine on the download page.

Cloud-based emulators and simulators

If you are not able to use the emulators and do not have access to real devices, then cloud-based emulators are the next best thing. A big advantage of cloud-based emulators over real devices and local emulators is that you are able to automate unit tests for your site across different platforms.

  • BrowserStack (commercial) is the easiest to use for manual testing. You select an operating system, select your browser version and device type, select a URL to browse, and it spins up a hosted virtual machine with which you may interact. You are able to also run multiple emulators in the same screen, enabling you to test the look and feel of your app across multiple devices at the same time.
  • SauceLabs (commercial) enables you to run unit tests inside of an emulator, which may be really useful for scripting a flow through your site and watching the video recording of this afterwards on various devices. You are also able to do manual testing with your site.
  • Device Anywhere (commercial) does not use emulators but real devices which you are able to control remotely. This is very useful in the event where you need to reproduce a problem on a specific device and are not able to see the bug using any of the options in the previous guides.
