Do you need to access a smartphone browser emulator on your PC to test the mobile version of a website you are interested in? Maybe you are a web developer, or you want to become one, and you need to simulate a mobile browser for the project you are working on. Regardless of your reasons, here is how to access a mobile browser emulator in Google Chrome, Mozilla Firefox, Microsoft Edge, and Opera:

How to turn on and use the mobile browser emulator in Google Chrome

In Google Chrome, navigate to the website that you want to view in the mobile browser emulator. Then, either press the CTRL + SHIFT + I keys on your keyboard or, with the mouse, click the three vertical dots in the top-right corner to open the “Customize and control Google Chrome” menu. Choose More tools, followed by Developer Tools.

Click or tap on the “Toggle device toolbar” button (it looks like a smartphone next to a tablet) or press CTRL + Shift + M on your keyboard. This activates the device toolbar where the mobile page is loaded. By default, the device toolbar uses a Responsive template for the site you loaded. Click on it and choose the mobile device that you want to emulate. Your options include many iPhones, iPads, Surface Duo, two Samsung Galaxy devices, and a Moto G4 mobile browser simulator for PC.

TIP: Unfortunately, you can use the CTRL + Shift + M keyboard shortcut only after enabling the developer tools.

Navigate the site you want to test, switch between the different smartphones and tablets, and see how it looks. When you are done, press the X (Close) button in the top-right corner of Google Chrome’s developer tools to get back to the standard desktop browsing mode.

Firefox enables the Responsive Design Mode. At the top of the window, you see the parameters used by this emulation mode. If no device is selected, click or tap on Responsive to open a drop-down list with devices available for emulation, and then choose the one that you want to simulate.

You can simulate the mobile browser for many iPhones, the iPad, the Kindle Fire (Firefox is the only browser to offer this emulation option), and Samsung Galaxy S9 devices.

Are you happy with the mobile browser emulation options available?

Now you know how to emulate all kinds of mobile devices in your favorite web browser. However, you might notice that most web browsers offer the same emulation options that favor iPhones and iPads. If you want to emulate a modern Android smartphone or tablet, your chances are pretty slim, even in Google Chrome - the browser developed by the company behind Android. If you want the best results, you might need to use two browsers for this task: Chrome and Firefox, or Firefox and Edge or Opera. Before you go, tell us what you think about the available options.
