This summer Google previewed a way to run Android applications on Chromebooks using ARC — App Runtime for Chrome. At this time there are only a handful of applications that work on Chrome OS through official channels. However, there are tools and workarounds that allow users to run their favorite Android applications on Chromebooks. One of the applications that works well on Chrome OS is the Opera Mini browser.

It might sound a bit insane at first — why would you want to run a browser inside of a browser? Beside the mind-blowing “inception” factor, using Opera Mini on your Chromebook can actually help you save bandwidth when you are browsing using a cellular data plan. Developers can also utilize this Chromebook capability to easily test websites and see how well the web works with Opera Mini. Besides all that, it is a fun hack to play around with.

  1. The Opera browser has been listed as a “tried and tested direct alternative to Chrome”. It scores close to Chrome on the HTML5test, which scores browsers’ compatibility with different web standards.
  2. The Chrome-Based Browsers Worth Using: Opera, Vivaldi, and Chrome Portable. There are, of course, exceptions to every rule. Some browsers are solid alternatives to Chrome, Firefox, Safari, Edge, and Internet Explorer. Opera, for example, has been around in one form or another for a long time, with the first version of Opera being released back.

Interestingly enough, the Chrome Extensions to Opera icon doesn't appear when you visit that page. Don't worry, you can still install the extension by simply clicking Add To Opera (Figure C).

Running Opera Mini on Chrome OS

Here’s the fastest way to get Opera Mini running on your Chromebook, using an Android device and a custom runtime called ARChon (the difference in runtimes is explained later in the article):

  1. Download Opera Mini and the ARChon Packager onto your Android device from Google Play. (Alternatively, the Opera Mini APK can be downloaded here.)
  2. Download the appropriate ARChon runtime to your Chromebook from GitHub.
  3. Use the ARChon Packager on your Android device to convert Opera Mini for your Chromebook. This will generate a ZIP file. Transfer the ZIP file to your Chromebook. Use the “Tablet mode” and “Landscape” orientation when you are converting the application to get the best experience out of Opera Mini.
  4. Unpack both ZIP files (the runtime and the application), navigate to chrome://extensions/, enable “Developer mode” and load the two unpacked directories as “Unpacked extensions”. Make sure to load the runtime first. After you load the two directories just press “Launch” in the Opera Mini extension. The application will also be added to your Chrome OS launcher.

If you already use the official Android applications on Chrome OS, follow the instructions on GitHub to get Opera Mini working with the official runtime. At this time the official runtime can only run up to four applications on Chrome OS. If you do not have an Android device, then obtain the Opera Mini APK file and follow the instructions of the chromeos-apk project to get Opera Mini working using a Node.js conversion tool.

Most Opera Mini features, such as “Downloads” and “Find in page” work really well on Chrome OS. When you restart the application, your settings and history get saved. If you remove and reinstall the application, you get a fresh copy with all settings reset.

Most of the screenshots in this article are taken on a Chromebook Pixel. However, using the ARChon runtime for 32-bit and ARM devices you can try out Opera Mini on older hardware. This screenshot below is taken on a 32-bit Samsung Series 5 Chromebook from 2011:

The Technology

Opera Chrome Os

The ARC (App Runtime for Chrome) is powered by the Native Client technology. This allows ARC to execute native compiled code in the browser. In this case, the Opera Mini application window is a basic HTML page with an embedded Native Client plugin component.

The runtime ships in three different flavors, for 64-bit, 32-bit and ARM processors. ARC consists of an ARM instructions translator, which allows Android applications to run in the plugin environment. There are also several libraries that emulate the Dalvik Virtual Machine and graphics hardware.

Opera Chrome

The custom runtime, called ARChon, is a forked version of ARC. ARChon is developed as part of the chromeos-apk project and allows running an unlimited number of Android applications on Chrome OS. ARChon also works on some Linux, Windows and OS X devices — this means you can try running Opera Mini on your desktop machine.

Currently it is not possible to run other complex browsers in these runtimes because of the native library requirement. Opera Mini does not have issues with native libraries and works outside of the box. It is also possible to tweak the application environment by editing the manifest.json file in the application directory. You can make the Opera Mini application window resizable or make the browser open files with different extensions. In addition, developers can turn on ADB (Android Debug Bridge) to take full control fo the sandboxed emulator for this specific application. The list of available runtime options is documented on GitHub.

Adding the Install Chrome Extensions to Opera.

In the past year, I've made the switch from Firefox to Chrome to Brave to Vivaldi to Opera. It's been a long journey, but, at least for the time being, Opera is it. During that migration, I wound up collecting a few extensions that made getting my work done a bit more efficient. Unfortunately, some of those extensions aren't exactly 'cross-platform.'

One particular extension, unavailable to Opera, had become a must-use for me, so I had to figure something out. After a bit of searching, I came across an Opera extension that allows you to install Chrome extensions on the browser. I quickly installed it and gave it a test. It should come as no surprise that the extension worked like a charm. Once installed, I could then add any Chrome extension I needed to Opera.

Let me introduce you to this handy bit of magic.

What you'll need

The only thing you'll need is a running instance of Opera. You do not need Chrome installed to make this work. This process will succeed, regardless of the operating system you are using. Of course, it is limited to the desktop version of Opera, so don't bother attempting this on your mobile version. You'll also need a Google account and to be signed in to that account with Opera.

How to install the necessary add-on

Open Opera and point it to the Install Chrome Extensions add-on page. Once there, click Add To Opera (Figure A).

The installation should happen almost instantaneously. When it completes, you should see a new icon in your Opera toolbar (Figure B).

How to install a Chrome add-on

Let's say you want to install the Grammarly extension--which doesn't have a version for Opera. Point the Chrome browser to the Grammarly Chrome extension page. Interestingly enough, the Chrome Extensions to Opera icon doesn't appear when you visit that page. Don't worry, you can still install the extension by simply clicking Add To Opera (Figure C).

This will open the Opera Extension Manager, where you must confirm the installation by clicking Install (Figure D).

When prompted, click Yes, install and Grammarly for Chrome will be added to Opera.

And that's all there is to install Chrome extensions on Opera. For anyone that has come to depend on those handy add-ons, this could be a real deal-maker for the Opera browser.
